I have no significant comments on your configuration settings.
Things I might try is lowering the querytimeout and adjusting the threadpoolsize (up or down to see what happens) You can make sure your cachesize is large enough by checking for “flushing” events in the eventslog. I suspect 50mb is fine. Turning off logging will reduce query overhead, but only slightly. Tango2000 is cooperatively multithreaded. This means that as more queries come into the server, more CPU time is wasted processing them. This means that your server will fail in a more-or-less exponential way. In other words, if it takes double the time to process 10 requests over 1, the processing time doubles again at 15 requests – not 20. This curve makes it difficult to understand exactly how Tango2000 is going to behave under load, where 7 threads might be fine, but 8 might be too much. Tango2000 can also only address a single processor – if you have an advanced license, you should deploy one service per logical CPU. The only other thing you can try is to reduce the overhead of each request – which what you were getting at with eliminating unnecessary columns, etc. You can also include in this task to optimize your SQL server – the faster it can return requests, the better. Lastly, to hunt down potential problem TAFs – write your own log. Write out at the start and then again at the end of each request. You can do this into your db if you wish. The start data should contain the request particulars (search args, etc). What will happen is that when your server dies you’ll have some start entries without end entries – now you’ll be able to know exactly what your server was doing when it went down, and hopefully you’ll be able to isolate a long running TAF or request or query.

Does the config file look okay to you? On a side note, I am going through every application and purging variables when not needed, getting rid of unneeded columns in searches, tightening up the code, etc. I do have some very basic questions, though. There are quite a few arrays being built and purged, mostly due to the client wanting to update multiple rows of data with a single click. Some of these arrays are being updated in a loop action rather then using <@ROWS>. Is there a performance hit or difference for using one versus the other? I think I know the answer to this one, but is there any advantage to running a different application pool on a subdirectory that is being used for administration for the client? I do run separate application pools on our other servers per website, but this server currently has one site that is divied up between public and admin. Thanks! _____ From: Robert Shubert [mailto:[email protected]] Sent: Tuesday, October 23, 2012 3:50 PM To: [email protected] Subject: RE: TeraScript-Talk: config file In my experience, this is caused by simultaneous calls to either the External Action or to @URL. Look through your TAFs and remove these types of calls.

Robert From: WebDude [mailto:[email protected]] Sent: Tuesday, October 23, 2012 1:30 PM To: [email protected] Subject: TeraScript-Talk: config file Hi Folks, I have several versions of Tera and the old Witango running on several boxes. The one box I am concenred about, unfortunately, is running an old version of Witango (2000 but fully patched with the lastest). I am wondering if one of you kind souls who have been around for a while could take a look at the config file to see if I am missing something. We are starting to get thread lock when the server gets busy. I have been pulling my hair out and trying to make it break myself but cannot find anything. I am most concwerned with memory vs what I have set up. I have actually seen the same userreference assing to 2 users from different IP addresses... not sure waht is going on. The box is running MS 2008 server web edition with 8 gigs of ram. It is the only thing we are running on the box. The DB is on another box running MSSQL 2008. Following is what I have. I am most concerned with cache settings, datasourcelife, itembuffersize, querytimeout, rerquestlimit and threadpoolsize. If anything is glaringly incorrect, I would appreciate a response... THANKS!
