I have two questions re compiling vs CPU + HDD throughput. CPU is Athlon-II, HDD is sata-3 + ZFS 1. When compiling world and some ports, neither CPU usage, nor HDD throughput (from gstat) is maximized (threads are defined in make.conf) and in many instances usage is very low. Is there a third parameter limiting the speed of the first two? 2. I have noticed that when compiling world resource usage fluctuates greatly, but that 10 and 11 both take considerably longer compared to 9 and that ccache is ineffective. Is this normal? PS. buildworld for both 10 and 11 halted at libiconv phase when ccache was enabled in make.conf. Proceeded without ccache. ----- FreeBSD-9.2-stable_amd64_root-on-zfs_clang-only-world -- View this message in context: http://freebsd.1045724.n5.nabble.com/compile-why-not-max-out-resources-tp5856479.html Sent from the freebsd-questions mailing list archive at Nabble.com.
