Description
When building with Make and multiple CPUs (or slow Makefile targets), sometimes things go a lot faster when using multiple commands at once with "make -j2". Support for that MacPorts is good.
Note that setting the number of jobs higher than e.g. "# CPU + 1" is a good way of using too much memory and making the build slow to a crawl due to lack of available memory and swapping instead.

comment:1 Changed 17 years ago by afb@…
patch adds the "buildmakejobs" setting, and the port variables "build.jobs" and "build.max_jobs".
Where build.jobs would override the users preferences (probably not recommended practice), and build.max_jobs can be used if the Port has a flawed Makefile that chokes on high -j...

Maybe toast the "build.max_jobs" altogether, and only use a portlocal "build.jobs 1" to override ?
