Hello, it does look like some parts of "guix pull" are parallelized as I was seeing guix-daemon's child guile take 200% CPU during :
loading... 23.5% of 511 filesrandom seed for tests: 1471011793 loading... 99.8% of 511 files compiling... 99.6% of 511 files So far so good, nice to use those cores that would stay idle. But... $ grep -c ^processor /proc/cpuinfo 3 So why is that not a ~300% is there only parallelism for 2 threads, or is it an unintended side effect and there is no parallelism ? If it had been ~100% or ~300% I would not have asked, but that 200% looks wrong one (missed a core) way or the other (no parallelism)... Thanks for feeding my curiosity... -- Vincent Legoll
