http://bugzilla.novell.com/show_bug.cgi?id=624849#c6 --- Comment #6 from Rickard Edström <[email protected]> 2010-07-31 17:14:33 UTC --- This reduces cpu usage to alot on this machine. However, when comparing BlockingCollection (mono master) running on .net, with the built-in .net 4 BlockingCollection, the mono version takes about 2% cpu, while the built-in does not show up at all (less than 1%). I looked at the code and it seems there are no usage at all of any signaling or something. The .net version probably uses ManualResetEventSlim or SemaphoreSlim to actually sleep until it is signaled (by adding an element). The mono one just spins alot which is plain wrong. (spinning should afaict only be used in a short while before actually waiting, but this behaviour is built-in to ManualResetEventSlim and SemaphoreSlim) -- 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 - [email protected] http://lists.ximian.com/mailman/listinfo/mono-bugs
