I've been testing this on and off (via commandline argument '--jobserver=…') when compiling gcc on a 16C/32T machine, both a single build and three different gcc versions at the same time and with a current Cygwin I don't see a difference either way. I'm back to using the FD jobserver since it seems to produce slightly better throughput, but that's hard to tell. I have some anecdotal evidence that some of this may be related to PID rolling over PID_MAX. This is no longer happening for me normally since that value got raised in Cygwin, but depending on how long you run your build machines it may be worth checking if that's a pattern you can observe as well.
