Installation packages
For Linux, Superserver download packages start with FirebirdSS, Classic/SuperClassic packages with FirebirdCS. The default run mode for Classic/SuperClassic installations is traditional, multiprocess Classic. To switch to SuperClassic, run the script changeMultiConnectMode.sh and answer “thread” at the prompt (for multithreaded). The script is located in the bin subdirectory of your Firebird installation.
For Windows, there is a combined installation package; you choose the architecture (Superserver or Classic) on one of the first screens. If you choose Classic, you can enable SuperClassic mode a couple of screens later.
