Description Yaniv Kaul 2018-08-29 17:28:30 UTC 
Description of problem:
Compilation right now doesn't seem to run make with the -j argument, allowing to use multiple processors and speed up compilation. This can reduce compilation time nicely.
Comment 1 Nigel Babu 2018-08-30 01:30:33 UTC 
As far as I know, we use make -j for all compilation. See: https://github.com/gluster/glusterfs-patch-acceptance-tests/blob/master/build.sh#L40

The only two places where we may not be doing this is the clang job and the lcov job. They're both run once nightly, so it doesn't really affect them as much.
Comment 2 Yaniv Kaul 2018-08-30 05:30:17 UTC 
I'm seeing ' make --no-print-directory install-am ' @ https://build.gluster.org/job/smoke/43261/consoleFull for example.
Comment 3 Nigel Babu 2018-08-30 05:57:17 UTC 
I don't know why that's the output shown on the terminal. That seems to have something to do with the Makefile code. Not the face that we're running it with make -j $n. On my machine when I run with make -j 4, I still see that line. That doesn't mean `make -j 4` isn't called by the build scripts.

nigelb@athena  ~/code/glusterfs  make -j 4
