Urm... so like if FreeBSD's getpid was 100x slower than Linux's then what exactly would it be? If FreeBSD's implementation is needlessly precise (and hence slow) for Python, then our platform should have a workaround "fast version" that Linux has. The "fast" version doesn't have to be the default (although linux's massive marketshare would prove otherwise) however our port should be patched to use the fast version. -Alfred > On Thursday, November 12, 2015, Vladimir Bogrecov <bogrecov@gmail.com> > wrote: > >> Hello, >> >> I'm developing a little project on Python 3.5.
