I thought that Classic wasn't available for Windows yet.

Is connection pooling done via the application or via firebird somehow?

OK, I'll try since I have been asking about that myself. Your milage
may vary.

First, get a copy of The Firebird Book (Borrie). In it is says that
the theoretical max number of connections per server is 1024 but you
may really get no more than 930 +/-.

If the HP Proliant is running Windows, then:
If you are going to use more than one CPU, then consider Classic
Server. It uses resources differently than SuperServer. SS must have
affinity set to only one processor or it may actually slow down rather
than speed up with more processors. There are articles available at
ibphoenix.com that tell you about the differences between the servers.

For more guidance on max number of concurrent users, search this list
for that. With connection pooling, you can serve a lot of users with
Firebird.

We use SS for most installations but are going Classic for any
installation with enough resources and multiple CPUs. Growing one to
900 +/- users through Xmas.

Hope this helps.
