Database adaptors such as psycopg do release the GIL while connecting
and exchanging data.  Apache's MPM (multi processing module) can run
mod_python and with that multiple python instances as separate
processes thus avoiding the global lock as well.

I really doubt that any performance difference will be due to the
global interpreter lock. This not how things work. You most certainly
have far more substantial bottlenecks in each application.
