Mark, I would bring up perfom on the web server, add all the CF counters, processor utilization etc and have someone hit the server and maybe that would shed some light. If their is a firewall in the picture, try browsing from a remote machine on the same segment without a firewall in the picture.

Unfortunately, we've been having performance problems with that exact (almost) setup. So, let me pick your brain, and everybody else here on the list, with some questions that I have. Web Server is Win2k, IIS5, PIII 400Mhz, 320MB RAM, CF5 Pro, T1 connection to the Internet We have a few apps running on this machine, but all but our Extranet are internal apps(very little usage). The Extranet is not very large either. I'm unsure of the daily traffic since we have no monitoring tools (except performance monitor) <cf_gripe>. But I know we only have around 200 users in the database and not all of them are hitting at the same time. So, the problem is that clients are complaining about the Extranet being slow. I can confirm this from home. It's fast for me at work since we're connected through a T3 internally and when I do a tracert from my workstation, I only have 4 hops compared to around 20 hops from home. I use NeoTrace at home and all the ping times are consistently low (20-50ms). I've also gone to the Web Server (I physically stood in front of it) and browsed our Extranet through localhost (this way, I take the network out of the picture) and the response time was very fast. I made sure to hit both pages without db calls and pages with quite a few db calls. We do use some session variables and we lock all of them. The session variables we have store a small amount of data so I'm not to concerned with that. I did find out yesterday that the Web Server is acting as a PDC. I'm somewhat limited in my networking knowledge, but from what I understand, Wind2k servers allow every server on the domain to authenticate users, thus taking on some of the tasks that a PDC in Win NT would do (correct me if I'm wrong). Currently, our network admins are removing that from the server and also double-checking every service that is running and disabling any service that's not needed. As per an Allaire article, I've changed the number of simultaneous requests from 5 (the default) to 3 (2 - 3x the number of processors) and I haven't seen a difference. I've also played with the page cache, but find that the default(1024k) is just as good as any other. In checking the server log, I consistently see Windows NT error 232 and 109 - I've researched this on Microsoft.com and understand that those errors may be with db calls. But I can't seem to track them down. I know this has been covered before on the various lists, but I've been unable to find a solution to these errors. That's about all I can think of as far as our set-up is concerned and the things I've done so far in my troubleshooting efforts. I guess my question would be: Out of everything I explained above, is there something obvious that I'm missing or not checking? In any of your experiences before, do the problems above point to a possible network or firewall problem? I'm just looking for some ideas on where to turn next. Thanks in advace for any input you might have, Mark -----Original Message----- From: Jim McAtee [mailto:[EMAIL PROTECTED]] Sent: Friday, December 28, 2001 1:16 AM To: CF-Server Subject: Problems like this everyone should have Two days ago we replaced a CF server with a newer, latest greatest, etc., etc. The new machine is running Windows 2000 Server and CF5 Professional. Most datasources are Access (I believe using MDAC 2.51 or later), a few using dbase (Merant driver) and a few using MS SQL Server 2000. The old server (NT4, CF4.01, MDAC 1.5 or so) had 512MB of RAM and routinely passed 420MB in memory usage). We cycled the CF Application Server nightly and that freed up at least 100MB in memory each night. The new server has 2GB (that's 2 GIGAbytes) of RAM. RAM right now is insanely inexpenive, even more so when I built the machine several weeks ago. So, now what do I see in terms of memory usage? Somewhere betwee 250MB and 290MB, never higher. I don't see the slow, gradual increase in memory consumption that I used to see. Who knows what to credit - newer ODBC drivers, ColdFusion5, or Windows 2000 itself. Whatever the case, it's welcome. What I'd like, however, is a means of turning all that unused RAM into increased performance. I've already got the CF cache set to 128MBytes, which should be overkill for something like 10MBytes worth of source files for the all CF templates themselves. Any suggestions? BTW, we had our single busiest day today, peaking at over 229kBytes per second (in a five minute sample) of outbound traffic from this single CF server. It hardly broke a sweat.
