  • after looking at the gnome-system-monitor while compiling a map i noticed that only one core was used... so i went searching and found this: http://en.wikibooks.org/wiki/Q3Map2

    Code: Select all
    -threads <number of threads Q3Map2 should use>

    * Specifies a number of threads to use during compiling. On Windows, Q3Map2 automatically detects the number of CPUs present, and sets the threadcount accordingly. The -threads switch can be used to override this behavior.
    * Linux users will need to manually set -threads in order to activate SMP support in Q3Map2.


    so by customizing the build menu and adding -threads n+1 (where n is number of cores or available threads (an single core P4 on sirtin chipsets has 2, an i7 has 8, C2Q has 4 etc etc ) you will make map compiling a lot faster..
