#49610: sbcl 1.3 fails to build ---------------------+------------------------ Reporter: glen@… | Owner: easieste@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: elcapitan Port: sbcl | ---------------------+------------------------ Comment (by glen@…): More information on this bug - either the OSX Yosemite default setting for Unix sockets, buffers, locks, mutexes, etc. are poorly optimized, or something was screwy regarding these settings for my personal machine, as making such system calls on my 2.4 GHz 12 core Mac Pro is clearly far slower than even on my 1.7 GHz Macbook Air. In any case, creating an /etc/sysctl.conf and using the optimized settings from the following website: https://rolande.wordpress.com/2014/05/17/performance-tuning-the-network- stack-on-mac-os-x-part-2/ not only completely clears up the sbcl build problem, but the build actually completes several minutes faster now than on the Macbook Pro. This is presumably because the more than 1 million locking mutex system calls that are generated by sbcl's sb-concurrency self tests can now complete without tripping the 60-second watchdog timer. -- Ticket URL: <https://trac.macports.org/ticket/49610#comment:6> MacPorts <https://www.macports.org/> Ports system for OS X
