Thanks both for answers, I read some articles you link and I'd to say - alot discussion around!
I also found some notes that mod_python use some technique other than GIL to allow multi-threading in Apache 2.0. Does someone know anything closer? Any links or so? Sorry I raise this old stuff again. Martin Just short notes: > Removing the GIL is easy, but then the interpreter crashes in cases of > simultaneous accesses to dictionaries, reference counters, etc. I know. But under mine conditions is impossible to share dictionaty or ref.counters so this do not happen. This dont happen neither on web server running simmultaniously several .py scripts (same conditions) > This is just not true. On a single-processor machine, the GIL does > *not* degrade performance.

I run several servers with hyperthreading processors and none of them runs two IISs or apaches just for load-balance python scripts.
