That's my problem as well. But be it 8 or 80, anything is better than the default of 1. Your example of 1 and it taking forever is the same as me for my size of projects.
I can't argue that everyone has 80 cores available, but I can argue that 8 is more reasonable than 1. > Sent: Thursday, October 22, 2015 at 3:50 PM > From: "Miller Henry" <[email protected]> > To: "Jason H" <[email protected]>, qt-creator <[email protected]> > Subject: RE: [Qt-creator] Sensible make -j X? > > That is right for you - I have a massive build farm (look into icecc, distcc, > or a commercial equivalent - they are awesum), -j 80 is the sweet stop for > me.
