I've noticed it too. We have seen more and more compilation time\nouts which means 7.5seconds of 1/4 of the compilation power tied up for\nthat long. I'm not yet sure if the timeouts are \"real\" or they're a new and\nfun way for node process control to fail.\n\nAs a huge hack I've bumped up the number of parallel compiles to 4 (from\n2), and allowed the number of back end nodes to go up to 6 (from 4). Most\nof the time we will be running on the minimum of two; only if CPU spikes do\nnew nodes come up. So far I've not noticed these 7.5s timeouts being CPU\nbound. My money's on some nasty NFS caching problem now I think about it...\n\nThanks for raising this. We also have grand plans to improve fairness in\nthe queueing too, but that's a bit more off.\nOn Tue, Jul 25, 2017 at 4:43 AM, Tilka <notifications@github.com> wrote:\n\n> Compilations seems to have gotten slower compared to, say, a few months\n> ago.
