I don't have a SRP implementation in Jaybird yet, and the tests I ran where using the Jaybird wire protocol implementation, not using the native client library, so that isn't the reason. And as you can see in my previous message, Firebird 3 is once again faster than Firebird 2.5.2 now the 'create slowdown' has been fixed.
