Hello,
building gcc in parallel (make -j): works ok
installing gcc in parallel: not necessary (used to fail regularly, but I
haven't tried recently)
running the testsuite in parallel: not so parallel
On an 8-core PC, for a c,c++ build, make -k -j check leaves the computer
at least 60% idle (I looked at top periodically), and for a huge part of
the time it uses at most 2 cores (and often only 1).
Since it looks like the testsuite is supposed to run in parallel, I wonder
if I am doing it the wrong way, if there are options to pass or a
different command to run?
