I now have a very simple C# synchronous I/O application which is able to send (as before) 180ish requests. (It also runs fast on Windows) The issue causing the performance problems in both apps seems to be that I'm sending a message just after I sent one. If I instead use the alternative[commented] implementation of Write() in the code linked, it works very fast under linux as well. Maybe this is intended behaviour for sockets on linux, or it could possibly be a mono bug? Anyways, the original description for this bug apparently is inaccurate as it stands.

So I guess it's not epoll related :/ But the fact remains it runs a lot faster on both Mono/Windows and on an old machine with Mono/OSX, so should still be Mono/linux related, probably? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the QA contact for the bug. ___ mono-bugs maillist - mono-bugs@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-bugs
