--- Comment #274 from Pierre-Loup Griffais bugs.winehq.org@plagman.net 2013-01-02 15:25:24 CST --- Hi Christian,
Thanks for giving it a try! The results you're observing look in line with my expectations; apps that make heavy use of dynamic buffers should have no change or even a slight performance hit with threaded optimizations forced on, but a gain with the patch. Other apps should exhibit the same gain before and after the patch.
I should add that if anyone tries to perform the same experiments, make sure to set WINEDEBUG=-all as the synchronous GetError calls completely defeat threaded optimizations otherwise.
Let's take your other question offline to minimize noise in this already cluttered bug.
Thanks! - Pierre-Loup
