Re: [gentoo-user] emerge -j, make -j and make -l

[Michael Mol]

Quick update...I now have two of these things set up in a distcc cluster
with my Phenom 9650. ~530 packages in 228m 34s. There's an even larger
initial explosion of parallel emerge jobs, but it spreads out very
nicely...I may have to increase the -j parameter in MAKEOPTS. I'm also not
certain if distcc is properly deferring jobs to the local host, but I got
the impression the local machine was getting a doubled workload when I had
127.0.0.1 in/etc/distccd/hosts.
