18:40:40josheusually I use it to host cross-builds
18:42:23stassatsbuilding sbcl is probably the only thing where i can benefit from more cores, but if it just goes from 50 seconds to 30 it's probably not worth it
18:44:44stassatsshould have better single-core performance too, but the next year should be even faster
18:44:53stassatsand then the next year after that, and the next
19:08:38stassatsbut i hit a fixed bug in sb-fasteval
19:21:11stassatsit would be more useful to time make-host-2 for scaling, although all the serial bits are important as well
19:22:32josheI thought timing a parallel build under clisp would make the differences more obvious, but now I'm bisecting to find the last commit that broke clisp hosts
19:23:01stassatsSBCL_MAKE_JOBS=-j160 => 120% cpu 5:42.97 total + SBCL_MAKE_PARALLEL=160 => 532% cpu 2:26.69 total
19:36:41stassats(that's make-host-2.sh without make-genesis)
19:40:50stassatsso it does seem to scale to 12 cores, but since that's the only part of the build that scales well, the total times get little improvement
