Whatever is default on 14550 didn't make a very nice noise while compiling
on my FreeBSD box. Load average was 0.11, and one of the disks was thrashing
a lot. [Unfortunately I have upgraded to hard disks without LED jumpers, so
I can no longer use the front panel blinkenlights to say whether it harassing
the source directory, /tmp, swap or /usr]
Maybe I should figure out how vmstat works, but I have my suspicion that it's
hammering the machine in the wrong way, and maybe it could trade using more
memory for more less disk access in order to compile faster.
[Then again, more memory => swap => disks, and as best I can tell on FreeBSD
less memory => free memory used as extra disk buffers, so the OS is doing its
best however you config things]. Or am I barking up the wrong tree?
