SOT: SQL Server Performance
Hi. I have a SQL Server running on: DELL PowerEdge 2950 4 GB Memory 1 Processors with 4 Cores Windows 2003 Standard - 32 bit ...and one 20 GB database. Normally, everything runs very quickly. In certain edge-cases such as: user requests 14 month report resulting in query joining 400,000 rows and 15,000,000 rows and...etc...SQL Server takes about 1 minute to return results. I've optimized the database and optimized the SQL and Database Engine Tuning Advisor has no more recommendations for me. I have the following three hardware improvement options and need to quantify (as much as possible) performance increases that'll be realized by implementing each: - add a second Processors with 4 Cores - upgrade memory from 4GB to 8GB and move to 64 bit Windows Server 2008 - increase number of hard drives to achieve RAID 10 Suggestions for a tool and/or some documentation that'll help with this? Google has not produced anything useful yet... -- John Bliss IT Professional @jbliss (t) / http://www.brandiandjohn.com ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:335845 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: SOT: SQL Server Performance
The Database Engine Tuning Advisor only gets you so far and some of the recommendations it generates are bad recommendations. For example, it might suggest redundant overlapping indexes. It currently takes a human to properly set up indexes. Your best bet is to find the bottleneck and try to quantify how much that bottleneck is impacting server operations. It would be hard to quantify any benefit from upgrades unless you know what the bottleneck is. Adding a CPU if the existing CPU never gets above 10% utilization wont do much. You can find bottlenecks using a number of methods. Wait stats would be the first thing I would check. In my experience, the hard drive is often the bottleneck. If your budget is limited I would make a guess that it is better to add more drive spindles than add another CPU. If you only have one drive array in your server that can be a problem, even if it is RAID 10. Adding RAM takes pressure off the hard drives and is usually a good idea. 4 GB is considered a small amount of RAM for a production SQL Server box. Even 8 GB might be too little depending on what you are doing. -Mike Chabot http://www.linkedin.com/in/chabot On Thu, Jul 29, 2010 at 8:40 AM, John M Bliss bliss.j...@gmail.com wrote: Hi.

Re: SOT: SQL Server Performance
Mike had a lot of good comments. How dynamic is your data? Is it constantly being updated? If so, do you need real-time query results? You need to balance the creation of indexes (as many as possible on a relatively static server) with the fact that indexes can slow down insert/update/delete operations. It sounds like it's your select statements that are slow so have you gone through all those queries and indexed everything properly? If so, I'd be surprised if you're not running out of RAM with only 4GB. This of course leads to dropped indexes, which leads to poor performance. Analyze the RAM usage of your SQL Server, especially once you've tuned your indexes. Then buy (more than) the amount of RAM you'll need. Don't automatically assume that 8GB will be enough because there's a good chance it won't be. Regarding cores, are you going to have to run this app under load? Will you have multiple people requesting the same queries? Can you cache results? If you have a query that takes even 20 seconds to respond and you can't cache the results, and you expect to have multiple concurrent users, then you'll run out of cores very quickly. If you don't need real-time data, or your data is fairly static, you can also look into Microsoft Analysis Services. - Andrew. On 2010-07-29, at 08:40, John M Bliss wrote: Hi.

Re: SOT: SQL Server Performance
As an adjunct to the advice you've already received (which is excellent I might add), I always recommend looking at the business use cases for reporting. Are these reports ad hoc reports or are they known reports that you can schedule ahead of time, execute during off hours, then save the results of to deliver to whoever needs it? Can you do a replication setup to a db server that is just set up for reporting and remove the load from the main db server? There are plenty of technical solutions, like adding more ram, that are available but be sure to also look at business process options that might be available as well. A good deal of the time you can save things by reworking some processes instead of just adding more hardware and end up making people happier in the long run.

RE: Server Performance
2 things for you. First, check the DB for blocks and locks - about 9 times out of ten queuing requests are due to DB requests that are hanging. For some reason we web developers bang our head against CF over and over thinking there is something we can do on the web server to solve problems that exist on the DB server :) Secondly, If you are already running perfmon then you can get the information on which site is busiest (or at least handling the most requests). Choose web service and then Current connections and all instances. Use the report view (the little page icon next to the chart icon on the toolbar) it is clearer. Oh... current connections is appropriate for Wind2003 and above. For windows 2000 use current anonymous users. What you should see (using the report view) is a horizontal list of all your sites. The _total will be the first item. On a busy server you may need to scroll to the right to see them all. You can click on them and delete the ones you know are not the problem. Even though seeFusion and fusionReactor are great tools, I set up saved Perfomon mcc's for all my windows servers - in fact you can view the counters remotely (if you have the right domain rules in place) and you can see more than one server at a time in the same perfmon instance. Granted it is less introspective than one of the Java tools - but for a quick glimpse of a server to answer the question - how busy is it - in real time, it's handy and easy. -Mark Mark A.

Is is possible? It is quite possible, the way CF and HTTP servers handle files. Also some people are still sending files in BMP format. Is there something I can do about it? Not I a m aware of.

RE: Image upload impacting web server performance
Absolutely. Large file uploads has a measurable impact on the server's CPU usage and memory usage as the file chunks are uploaded and them copied. One thing you can do is add a bit of restrictions on the file size. Unfortunately, the client can't know the size of the file before upload. Your only option that I can see is to make an obvious prompt to your users about file type(s) and size restrictions, then enforce it on the server side by checking the fileSize property of the uploaded file. -Original Message- From: MJ Frauenaheim [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 24, 2006 12:28 PM To: CF-Talk Subject: Image upload impacting web server performance I have a community site where members can upload photos of themselves.

RE: Image upload impacting web server performance
Perhaps the server doesn't have enough RAM/Threads? I can't imagine a file upload freezing up the server unless you're doing some sort of image processing on it (such as resizing). Just uploading a file is not a very cpu intensive operation, and even if it's a file that's several MB long, you should have sufficient ram to handle it. Now what happens if you have 10 users doing it at the same time is another story. But 1 file upload should not noticeably slow things down.

Not I a m aware of. Bowsers are too picky about security. Javascript has no access to any information about the file selected for upload.

RE: Did my own CF/SQL Server performance testing, my world is tur ned upside down.
Well, OK, not that dramatic, but every DBA I have ever known has told me that if you want performance, you use stored procedures. My quick test this evening has me rethinking that. Just a warning - quick tests are often worth about the time you put into them. The straight query using CFQUERYPARAM was consistently the fastest. I fully expected this to be the case when compared to using a straight query without cfqueryparam, but I was really surprised to find that the stored procedure was consistently the SLOWEST. Has anyone else found this to be the case? I'm really thinking about ripping out all of my SP's and just using queries, it would make my life easier on a number of levels. I have all of my queries as methods in a CFC, so code reuse is about the same that it would be when using a stored procedure. First, this may simply be due to the database drivers you're using. You might try running your stored procedure through CFQUERY instead. Or, you might try newer database drivers, if they're available. You might, just for curiosity's sake, try running your queries and stored procedures through Query Analyzer, to see how they compare then. Second, prepared statements using bound parameters are typically as fast as stored procedures in most modern databases. There are still reasons why you still might want to use stored procedures over prepared statements, though, such as the ability to provide additional database security, and the ability to provide a database interface to multiple applications. Third, the reason that stored procedures and prepared statements are generally faster is because they allow the database to cache an execution plan, so that the next time the query is run, the database can reuse the plan rather than calculating a new plan.

Re: Did my own CF/SQL Server performance testing, my world is tur ned upside down.
It's worth mentioning that there is some overhead for calling a stored proc that isn't involved with straight queries, though it should be minimal. Where stored procs REALLY shine is when you've got a query whose result is only used for some logic driving another query. Using a stored proc in that scenario will save you DB roundtrips, which is huge (at least if you're hitting the DB across a network, which will pretty much always be the case for larger apps thare care about performance). The other argument for stored procs is security: you can limit application access to invoking stored proce, and thereby prevent any ad hoc access to the DB. Outside those two very specific situations, prepared statements as inlined SQL is almost always a better choice. cheers, barneyb On 5/21/06, Dave Watts [EMAIL PROTECTED] wrote: The straight query using CFQUERYPARAM was consistently the fastest.

Re: Did my own CF/SQL Server performance testing, my world is turned upside down.
here's what i have found... i agree. when it comes to small queries like that with NOT MUCH LOGIC involved. When it comes to a larger Stored Proc with LOTS of gobbledeegoop, i think it changes then. but yeah, for the most part, i refactored most if not all of my smaller queries into straight sql code, with cfquery. tw On 5/20/06, Pete Ruckelshaus [EMAIL PROTECTED] wrote: Well, OK, not that dramatic, but every DBA I have ever known has told me that if you want performance, you use stored procedures.

Not sure if the product support team has a technote published on this yet or not, but check out this Microsoft KB article regarding IIS6 performance. This issue does affect ColdFusion MX 6.1 running on IIS6.

Re: Server performance
2-300 users, 500k cf hits/day is not all that much (it's a good amount, but it's not at all abusive). Also, it depends on how you measure concurrency. Some people do it by # of cf sessions, some by DB last activity time, and others by whatever their log stats says. Others would argue that you can't measure user concurrency, but hits/sec concurrency. If you talk to CF support engineers, they will ask you about concurrent hits. You won't find much better performance with CF Enterprise, unless you're sending mass amounts of email. I have an app that runs way more traffic on cf standard, no slowdowns. What it really probably boils down to is your application. I know you can't share your code (not even the nasty parts), but that would be helpful. Perhaps we could help a bit. It sounds like you need to do some performance tuning. Perhaps re-evaluate some of the things you do, and they way you go about doing these things. Reduce the number of database transactions and move queries to stored procedures. Look for ways around other external processes like cfhttp, cfftp, cfmail, cfpop, image processing and so on. If you can make these processes asynchronous, do so. Remove or replace any CFX tags. Make sure you have all the CFMX patches (though I don't recommend the post-6.1 updater, we had some sqlserver driver problems). Turn on cfm page caching options. Begin caching queries wherever possible. good luck -nathan strutz http://www.dopefly.com/ JB McMichael wrote: I am currently running CFMX 6.1 Standard Edition with the updater installed on a Win2k3 server, with IIS, connecting to a SQL Server 2000 db that is on another computer.The web server itself is a pretty beefy machine, and it is running one website that is fairly complex.The site usually has 200 to 300 concurrent users and averages about 500,000 page views a day.

Server Performance
Hi Some application/request is killing my server (running intranet). And almost everyweek my server stops working (for intranet) and when I check the server there is message OUT OF VIRTUAL MEMORY. I want to log all applications which are taking longer than 2 minutes (to find the culprite one). How can I log all requests for my intranet which are taking more than X time and also that would be great if I define time span as well.

Re: Server Performance
Go look in the CF administrator under logging You should find a setting in there that allows you to Log slow pages taking longer than n seconds Tick the box and set the number of seconds to 120 seconds.

RE: Server Performance
On CF5 (and cf4.4 I think- can't remember exactly) in the CF admin pages and go to 'logging settings' (under the tools option in the top left). On that page you can set the server to record pages which take longer that x seconds. hth, Alex -Original Message- From: Shahzad.Butt [mailto:Shahzad.Butt;JJFastFood.com] Sent: 28 October 2002 13:27 To: CF-Talk Subject: Server Performance Hi Some application/request is killing my server (running intranet).

RE: SQL Server performance
It's not my area of expertise, but you might look at the recent long discussion on using the BLOCKFACTOR attribute of CFQUERY. It allows you to affect the efficiency of communication between CF and your db (in some situations). -Original Message- From: Joe Sheble aka Wizaerd [mailto:[EMAIL PROTECTED]] Sent: Friday, December 01, 2000 9:24 AM To: CF-Talk Subject: SQL Server performance I know this issue has probably been talked about in the past, but I'm new to the list... I'm certainly NOT new to CF, been doing it for quite some time (over 5 years), but haven't played much with administration, just coding. I have a small performance issue that has only recently begun to be bothersome. I'm running CF 4.5.1 on NT4 in IIS 4 using SQL Server 7.0. The CF and IIS are on a dual PIII 450, 512MB RAM system and the SQL Server is on a DUAL PIII Xeon, 1 GIG RAM and the two are connected via a 100 megabit network connection. I have a simple database with 1400 records in it, all properly indexed... I run the following query in Enterprise Manager of SQL Server and it takes mere milliseconds... I run it through CF and it takes 1 minute 40 seconds. The data I'm looking at for this query has 1400 records... Ok, so first thing people will tell me is to retrieve a smaller set of records... well SQL Server is certainly capable of holding this much (and a whole lot more) data, and using it quite efficiently. A C++ program we have running on client machines accessing the same set of data take mere seconds to load. There is no additional processing being done on the page, just merely calling the CFQUERY... The OLEDB connection would be one optimization, but as I was reading through the OLEDB docs there seems to be major issues with missing functionality. Plus the messages in Allaire's own forums gives the impression that OLEDB is not quite up to snuff... So where should I be looking for performance tweaks? Oh, here's the query: CFQUERY NAME="qEmps" DATASOURCE="#DSN_Name#" USERNAME="#DSN_Username#" PASSWORD="#DSN_Password#" SELECT IDNumber, FirstName, LastName FROM dcp_Employees ORDER BY FirstName /CFQUERY Thanx! ~~ Structure your ColdFusion code with Fusebox.

SQL Server performance with CF

RE: SQL Server performance with CF
you can install dual NICs on the web server and create a dedicated network connection btwn. the web server and the DB server (100mb or more pref.). If the web server is the only thing using SQL server, then you take that traffic off the general network, freeing up bandwidth. /s -Original Message- From: Chris Lott [mailto:[EMAIL PROTECTED]] Sent: Monday, September 25, 2000 12:19 PM To: CF-Talk Subject: SQL Server performance with CF -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Are there ways to optimize the connection between a CF server and an SQL Server machine?

RE: SQL Server performance with CF
Are you noticing problems in this respect? Usually until you receive lots of traffic or are on a busy switch or hub, this isn't an issue. But as traffic grows, you may wish to make a few changes. -Original Message- From: Chris Lott [mailto:[EMAIL PROTECTED]] Sent: Monday, September 25, 2000 9:19 AM To: CF-Talk Subject: SQL Server performance with CF -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Are there ways to optimize the connection between a CF server and an SQL Server machine?
