IME, using a number larger than the actual number of CPUs slows the build a lot, due to cache thrashing. Modern CPUs perform well only with hot caches, and each switch to the "other" build process will replace the cache contents. The OP said that rpmbuild was using the CPUs properly and ran fast, but earlier parts of mock were not and ran slowly, and take most of the time. He indicated that most of the time is spent extracting the build root from the cache. -- ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/> -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
