= Speed up compilation =

If your host system has 1.5GB RAM or more, you can use tmpfs filesystems to speed up compilation.

(You kernel must support tmpfs RAM filesystems)

edit your /etc/fstab and add :
{{{
none        /tmp        tmpfs   defaults,size=512m,mode=1777    0   0
none        /storage/btux/sources tmpfs defaults,size=1024m,mode=1777 0  0
}}}

Be sure to replace /storage/btux/sources with the full path of your btux/sources directory.

then mount them :
{{{
mount /tmp
mount /storage/btux/sources
}}}

Note : some distros comes with /tmp already mounted as a tmpfs.

Benchmark : On an XP 3200+ CPU, building the tools takes '''56m22s''' (with /tmp as tmpfs) 7200rpm HDD, while it takes '''44m29s''' with both /tmp and butx/sources as tmpfs.
