Subject: Re: more questions about threads... From: Erik Naggum <erik@naggum.no> Date: 2000/04/05 Newsgroups: comp.lang.lisp Message-ID: <3163944702587593@naggum.no> * Tim Bradshaw <tfb@cley.com> | I'm not sure what if anything this says, except that solaris has fast | thread creation perhaps. I'd kind of expect their thread impl to be | pretty good because their market is big multiprocessor machines. I'd also expect Sun to want a "favorable demo" effect that shows this. Linux has made fork exceptionally fast (my experience is that PIDs are used up about three times faster under Linux than under SunOS 4.1.3_U1, with equivalent work being performed on the systems), and has implemented the performance sensitive parts of vfork in fork. ironically, it now appears that threads have to do _more_ work than processes because they _share_ the memory and a bunch of other stuff that fork splits off into objects with distinct identity. #:Erik
