How many users can connect to Firebird simultaneously?
There is no limit in the Firebird server - it is limited by the resources in your server. However, most operating systems have a hard-coded limit of 1024 connections per TCP/IP port, and there are known cases of Firebird working with that many users (typically when classic client-server application is used over Internet).
If you need to serve more than 1024 clients, you should use some connection pooling technique - build a multi-tier application, and have multiple users use the same connection.
