I generally tend to run my builds behind the screen
port these days, which helps (screen implements a
virtual display buffer that disconnects screen updates
from the display client and the slave pty). Another
optimization worth noting is running make -q, which
silences a lot of that spam (urban legend has it that
the synchronization in parallel makes to write the build
messages causes noticeable amounts of contention).
I regularly use -s. With the pipe code being completely
Giant-free, I don't see a significant performance difference
anymore on an SMP machine when the output is not supressed.
Ah, I meant -s. And, that is good news. I am still running
on a 4.x system most of the time, and (sigh) Linux 2.4.x the
rest of the time.
