From: "a dot darovskikh at compassplus dot ru" <sourceware-bugzilla@sources.redhat.com> To: glibc-bugs@sources.redhat.com Subject: [Bug libc/207] New: ucontext is very slow. Date: Mon, 07 Jun 2004 08:45:00 -0000 [thread overview] Message-ID: <20040607084537.207.a.darovskikh@compassplus.ru> (raw) We use ucontext related functions in our project. We port it from Windows, where we used to deal with *Fiber functions. During the tests we discovered that our task engine on linux is near 10 times slower than windows one. Here are two small examples on context swapping on windows fibers and unix ucontexts. Unix one works near 5 seconds against 0.4 on windows one. Is it possible to improve perfomance? Thanks in advance. Alexander Darovsky. -- Summary: ucontext is very slow.
