Long-running tasks (at least on Windows) seem to hog the cpu so that other
tasks are slowed down. This may be more evident hen 'everything' is run as
one or more SP's than when the clients run seroes of small tasks. I
haven't tested lately, but I've found that letting the client "interfere"
will let everyone get a timely piece of the cake - and it keeps people happy.
Maybe a multi-cpu server running Firebird CS on Linux would be a better
choice (compared to Windows).
It is claimed that IB/7 handles this a lot better than previous versions.
