Summary of wall clock time from clean "time make" for 20021125:
dk, gcc2.94, debian 3.0: 8 min : dual 1.4GHz P4 Xeon, 512 MB RAM, 256KB L2 cache each
dk, gcc3.2, red hat 8.0: 16min 1sec: distcc with dual 650MHz, 750MHz laptop, and a 1.1GHz celeron 17min 21sec: dual 650MHz PIII, 400 MB RAM, 256KB L2 cache each, 7200RPM disk 19min : 1.4GHz Athlon, 256 MB RAM, 256KB L2 cache 30min : 750MHz PIII laptop, 400 MB RAM
mf, ? 16m56s : 1.8 GHz P4
ms, ? 30min : 900MHz athlon, 512 MB RAM "much faster than this with ccache -- was going to buy new motherboard, now I'll wait"
bm, gcc2.95rh, red hat 7.3: 47m0s : 450MHz Celeron, 128MB
jm, gcc3.2 47m41s : 550MHz athlon, 192 MB Ram
tl, ?: 180m : 300MHz Pentium II, 96 MB RAM
am, ?
180m : 133MHz Pentium I, 64 MB RAM
My impressions -- * gcc2.9x is probably a fair bit faster than gcc3.2 * ccache is a win * distcc is only a win if you have several equally fast machines * athlons don't do quite as well as their clock speed would indicate * dual processors go twice as fast as single processors (imagine that)
