I use python to execute some algorithms and no matter which python i use, and i have tried many versions, the cpu usage goes to 25% max. Why isn't python take advantage of the rest of my cpu resources? I changed the priority of the service from normal to high and later to realtime, with restarts in between but nothing changed.
Is there a way to make python use 50% or even more of my cpu ?
I want to build Python 2.7.8 on my Ubuntu 12.04 machine, which has Python 2.7.3 as default distribution. I would like to "install" Python 2.7.8 but isolate it from Python 2.7.3 - meaning, I don't want to interfere at all with the distribution's default Python.
