Non mi ricordo per quale via sono arrivato a questo interessante post sul forum Gentoo che parla di alcune procedure per velocizzare il sistema: [(HOWTO) Flying with gentoo](http://forums.gentoo.org/viewtopic.php?t=231170&start=0&postdays=0&postorder=asc&highlight=&sid=10654d5b41f8e4a48c412e710f050011)
In realtà non ho fatto grandi prove, ma spannometricamente ho notato un sostanziale velocizzarsi di tutti i programmi multithread (firefox, thunderbird, kde e ooffice… per dir poco…).
Vi consiglio di provare almeno questo:
> **Native POSIX Thread Library**
> This library, know as NPTL, can improve our system, because it’s up to 4 times faster than the standard LinuxThreads when creating new threads. You *should* use 2.6 linux headers, and a new version of glibc and gcc (~x86). To use ntpl you just have to recompile glibc with the USE flag “nptl” turned on.
> note: in order to use nptl you need gcc 3.x or higher installed.
