Clearly your definition of modern doesn't include my server... :) Just checked and the last build clocked in at 192 minutes. I need to make sure I have /var/tmp/portage symlinked back to a non-tmpfs location whenever I build it or else the system pretty-much dies from a lack of RAM. For kicks I tried to do better with distcc and EC2. That worked great until it started running a bunch of python scripts in the makefile - at -j15 or whatever I had it set to. Distcc really needs a solution for the fact that you can't pick a single optimum value for -j when gcc is only part of the build. Sure, the EC2 latency isn't great, but you can parallelize as much as you want, and for me the bigger benefit is not sucking down half a gig of RAM. Still, the build has gotten faster with time as the excellent g.o chromium team slowly strips out bundled libs. If you want a real eye-opener do a du -s * in the source tree for chromium and see where all the code is.
