VFP 6 Speed Issues on Network

I have a VFP6 app running on a brand new server. The app is running really slow. A simple click on a 'Next Rrcord' button takes 15-20 seconds to refresh the form. On the old server it seemed that whenever the 3rd or 4th user signed on to the system, the whole system slowed down. I had attributed this to the old server, but the new one didn't seem to help, in fact it is worse, everyone is now running slow. Many of the forms open 20-25 tables, some have table buffering and some have record buffering, and some of the tables have a couple of hundred thousand records. I've had other apps running at other locations with many more users and records with no problem. Can someone give me a generic list of where I should be looking (Reinstall fox runtimes, Anti-Virus, etc.) Is there a setting on the local computers or the server about the number of file or record locks, or number of files open. Just thinking out load here and searching for anything that might help? Would porting it to VFP 9 help?

No new ideas here. They are now running the app through Terminal Services which makes it fast, but causes other problems like no local drive access, etc. I have not had a chance to really investigate the issue at their site. Now that things have settled down after the new server installation, maybe I can do some more testing with the AV, etc. Good Luck, hope we find an answer!

Click to expand...

Send the local drives over via Local resources... We do, printers as well, with an 85+GB pure VFP database app with 200+ tables each containing about 25 Million records and 100+ users in TS running on a Windows 2003 server. It runs in nano seconds.
I would definitely check out Dan's suggestion regarding the NIC cards. Also I would run the complete app in every scenario in Coverage profiler to check where it’s slow or for redundant calls/loops...

Good luck.

To AnyGuy. Are you using Citrix? Are all the patches implemented? On our system (2003 SBS) we've had to use Appsence to downgrade the CPU usage, for a host of apps, 16bit and 32bit.

Nope, No Citrix here!
