Set -jN per machine and add stats for ccache #78

Closed vchuravy closed 6 years ago

vchuravy commented 6 years ago

Builds with ccache are better than from scratch, but they still take a lot of time. Add stats so that we can monitor whether our cache is big enough and increase the number of paralle make jobs.

One thing to note is that the fetch step currently takes about 1h on Windows, mostly due to the cleaning part. Jameson noted that this is a cygwin problem and we could sidestep this by calling delete on everything except the .git folder.

Yeah, these look like nice improvements. Thanks @vchuravy!
