Hi everyone,

and thanks for this beautifull project.

I'm creating this issue because we have got big differences in results using ib-aid test with firebird Super Server docker images
(jacob alberty for fb 2.5, fb3 and fb 4.0.2-4.05, official firebird image for fb5).
https://ib-aid.com/en/simple-insert-update-delete-test-for-firebird/#how_to_run_firebird_performance_test

Each test is executed individually on the same virtual machine, many times, without any specific configuration, and here are the results approx' :

FB2.5.9 :
INSERTS 12000/s
UPDATES 9500/s
DELETES 16100/s

FB 3.0.10 :
INSERTS 5500/s
UPDATES 1700/s
DELETES 1400/s

FB4.0.5 :
INSERTS 5500/s
UPDATES 1600/s
DELETES 1700/s

FB5.0.2 :
INSERTS 5200/s
UPDATES 1400/s
DELETES 1600/s

What could it be ?

Are there any default configuration differences that could cause this?

Thanks for all,
