Yeah, top typically shows 60-70% idle on the iMac while compiling,

OK -- now what about I/O and memory pressure? An idle CPU does not
necessarily indicate an underutilized machine (though I suspect that
is the case).
top -u should give an idea of pageins/pageouts. For I/O, I usually
find it useful to more judge the responsiveness of the machine when I
try to use it for normal tasks.
Clearly, we need to do a better job of using the local CPU when doing
distributed compilation. Yet, our testing has shown that too much
use of local resources can very quickly kill the usability of the
local machine. Worse, it can make distributed compilation
performance suffer greatly as the local machine is no longer able to
fill the remote queue.
