I finally got my desktop back together with a shiny new Intel Core i7 920, 6GB of DDR3. I haven’t overclocked anything yet and my entire build tree and operating system is on one 7200RPM drive. This thing is really fast for builds! I just built Firefox in less than 5 minutes. I did make -s -j16 -f client.mk clean then time make -s -j16 -f client.mk build and got the following output.
real 4m50.217s
user 2m44.854s
sys 0m55.450s
I used this as my mozconfig:
#John Ford's MozConfig file
ac_add_options --enable-application=browser
ac_add_options --disable-tests
ac_add_options --enable-official-branding
mk_add_options MOZ_CO_PROJECT=browser
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-@CONFIG_GUESS@
I should have done a build before I went to the new hardware as a comparison, but my old hardware is essentially the same as liberia and china over at CDOT.
