Question
slow performance with Visual Foxpro v8 on a Windows 2003 server
We are running a program called Sage Rainbow (which is a fundraising software) and is running on a Windows 2003 SBS server. If there is only one person accessing the software, it's quite quick but as soon as more users get on it (on average about 10) it really does start to slow down.
Of course, we did a test and installed the database on a local workstations and it flys.
Is there anything that I can do to optimize the speed of this software over the network?

I doubt you can do anything. The fast access, almost like working with a local installation, when only one user is active, could be caused by opportunistic locking (this is an OS level optimisation in the file system and works by caching). The only thing you can try is turn that off: http://support.microsoft.c
The effect this would have is, that the first user rather has the same slow experience, but on the other side it could help make it sufficiently fast for all.
Bye, Olaf.
we are running a foxpro application for our ERP system.
we've had the same issues running the application over the network, but in the end we had to setup a Terminal Server with the application installed locally on the C: or D: drive just to get some proper performance.
foxpro application over a network interface are generally problematic in my experience
this isn't really a solution, just some feedback
_Birkoff:
myths about foxpro data:
-clients cause lots of filehandles and locks: true
but
-clients pull whole files (DBF, CDX, FPT) over the LAN: wrong
It's not foxpro itself, but bad programming, bad data access design, unoptimized tables (indexing), that cause a foxpro app to be slow over the LAN.
If it works sufficient for you to turn that app into a Terminal Server app, that's fine. That may even be a solution to John Bowden.
The other thing that helps of course is optimize the LAN: Gigabit, analyze, if there are any bottlenecks in the LAN that make the fox app slow.
By the way, sharing the EXE on the LAN is also a bad idea, if not doing that in the way Terminal server shares an installation, but the EXE is simply file shared. Because then it's not only data access but also program execution taking bandwidth from the LAN. Install the app local, only install data central.

Try to disable anti-virus check on dbf files.
Does the application lock the whole file or specific records on saving?
