Subject: Use twice the hardware execution context to keep the system busy
X-Git-Url: https://git.zerfleddert.de/cgi-bin/gitweb.cgi/m1-debian/commitdiff_plain/14a89953f4035ec5dff0723b29af6fe28a41ab23

Use twice the hardware execution context to keep the system busy

15:47 < kov> Glanzmann, may be a good idea to replace the -j 16 with -j `nproc`?
15:48 < Glanzmann> kov: I always use nproc * 2. That is where the 16 comes from, but yes.
