Fast Question Multicore

[kero99]

Mangos support muticore in linux compilations? o what improvement have linux mangos compilations over windows compilations?

Thanks.

To use multi-cores to speed up the compilation just add the -j flag to your make command when compiling. This basically compile with multiple threads and utilizes the cores. An example of the command would be

make -j2

for dual core

make -j4

for quad core

etc.

Well the recommended -j argument value is (n*2)+1 where 'n' is the number of CPUs/cores.

So even for a singlecore CPU we shoud do -j3 ??

[kero99]

If i compile binaries with make -j4, mangos (mangos-realmd, mangos-world) support quadcore too or make -jX are only for the compilation process?

Thank a lot =).

I rather think it is n+1.

Oh, right. Maybe I remember it incorrectly or it was a typo in some old Gentoo documents. It makes more sense with CFS scheduler indeed.

No, you;ll only get compilation speed up. If you want multicore binaries, use mtmaps patch on your own risk.
