Yes,

I tried it, under load with Classic Server I get a LOT of:

KANGNKO Sat Feb 25 19:49:35 2006
Database: C:\WORK\NF5.FDB
page 30341, page type 5 lock conversion denied (215)

I know this means "deadlocks", but the SS does not exhibit this
behavior as often (difference in Locking scheme between CS and SS).

Also under Classic, the Application becomes very I/O Heavy
and requires twice the RAM (For Caching).

For this App, Classis is WAY slower and less responsive than Super Server.

thanks,

stan
