I have a W3K server with 4 GB of RAM running VFP 9 application by
80-100 users using Terminal Server. Performance is poor if more that 60 users are working. Task Manager Shows typically:

PF usage: 2.45 GB
Physical memory 3669388
Available: 1767416
System Cache: 1893012

CPU usage 10..90%
Mem usage for each vfp application is 9..30 MB

Maybe poor perfomance is caused by PF usage: 2.45 GB.
