>We have a VFP9 database running on networks. In some case, even with only 2 or 3 users and less than 50,0000 records in largest file, this becomes painfully slow. When one logs into the same databse in single user mode, the same system runs like the clappers (same time of day on network - thus it's not the network per se. The offending network has PCs running on Windows 7 Enterprise with Service Pack 1. The network runs on Extreme Networks switches (1 Gbit). Storage is hosted on NetApp.
