Firebird Performance Comparer (FBPC)

In my two presentations at the 20th Firebird Developers Day, I introduced firsthand the tool I created to help compare the performance between two Firebird servers (>= 2.5) in an easy and visual way.

This tool actually helped to detect a performance regression in Firebird 5 beta, which was resolved after I reported it to the core developers. The intention is to identify optimizer regressions or low performance issues in Firebird itself, or even the breaking of SQL commands due to new reserved words or syntax restrictions.

I’m making version 1.0 beta available for anyone interested. It’s a version that so far has been tested only by me, so it may and probably does have some bugs.

The FBPC runs on Windows and internally uses Firebird 5 RC1 embedded to store the tests and their results. When you run the application for the first time, it will display instructions on how to use it.

In summary, it helps you create a trace.conf to capture SQL commands executed on a Firebird server 2.5 or higher in a production environment. Then, the tool parses the file and collect the statements, allowing you to run them in a controlled environment of servers, specifying test rounds where the execution time between server1 and server2 is compared and displayed in an intuitive and visual way, enabling you to detect regressions or even commands that could not be executed due to new reserved words or syntax restrictions imposed in new versions of the DBMS.
