Did you ever check what this generates on Shippable? AFAICT they only
have one core for each docker image. I following the core+1 pattern
although that may not make as much sense for low core counts.
From the 'Job node info':
$ sudo docker info
Architecture: x86_64
CPUs: 2
Checking at 'ci' stage:
$ echo "container proc:" `getconf _NPROCESSORS_ONLN` `getconf
_NPROCESSORS_CONF`
container proc: 2 2
I think the correct cores+1 pattern should instead be:
make -j$(($(getconf _NPROCESSORS_ONLN) + 1))
So we stay building at full speed if Shippable eventually upgrade/allow
to use more cores.
For what it's worth using this pattern builds last on average <8min vs
>9min previously :)
