These applications (written in c# and using the FirebirdSql.Data.FirebirdClient.dll) basically retrieve records from the database, perform a special processing (IO bound not CPU bound) and update the database with the results.

We would like to run as much applications and threads as possible in order to speed up the processing of the database records but we do not known how many connections the firebird server can support. The applications and the firebird server will be executed in the same computer.

It is limited by the resources that you have Memory and CPU (the more the better)

Firebird can be capable to sustain more than 2500 connections with proper big iron servers
