With emphasis on the "roughly", I seem to recall that it took me several days to compile everything I wanted on initial system installation on machines of similar capabilities. But that includes significantly more than stage3, with long build time stuff like firefox, chromium, and libreoffice accounting for at least half that time. > > next month i'll be setting up a compiler farm with 3 other, similiar > machines which should help, will also be upgrading cpus to 4 or 6 core, and > have one machine that can upgraded for phenom and one i can update to > opteron, according to the board makers (it just needs a different bios). > > If i had the supporting bios any of my machines could upgrade to nearly any > AMD socket 2 or 3+ chip You seem to want to see how fast you can go, and that's certainly an interesting exercise. I've been there, too, but over the years have gradually retreated to a very non-aggressive compile setup. I've used distcc, made use of multiple cores, parallel make, etc. but have abandoned them all over time. It is quite possible to slow things down with improper setup, or with a local network with limited capabilities, so it takes a little time and experimentation to tune things properly. And it's possible to speed things up substantially, too. However, in my experience, speedups obtained this way can and do expose bugs in the build process. For me the personal keyboard time I invested in fixing things that broke in parallel wasn't worth the speedups I achieved. I, too, come from the punchcard and paper tape era, so even the very cheapest modern cpus run circles around the multi-million $ parallel supercomputers I used to buy and use. I now prefer just starting an emerge, and letting it take its merry old time. Gentoo's gotten good enough over the years that this almost invariably works. I'm not criticizing your speedup plans - by all means, have fun - but if you're just starting out in Gentoo, be aware that these speedups aren't necessarily a slam-dunk. John Blinka
