--- Comment #25 from Maurizio Oliveri 6tsukiyami9@gmail.com 2010-05-05 10:04:50 --- Ijust tried to build wine .43 adding -lmapmalloc to LD_FLAGS, and altough 3D apps run (I didn't try any .NET one though) there are some serious performance issues. I tried running 'time winecfg', and... using -lmapmalloc: Real: 24,83s User: 4,45s System: 0,81s Percent: 21% Cmd: winecfg reverting the patch: Real: 5,64s User: 0,48s System: 0,49s Percent: 17% Cmd: winecfg Both times, winecfg didn't have to update/create the .wine directory, I've removed it before both tests, used winecfg to create ~/.wine, then run winecfg again with the time command, closing the window as soon as it popped up. Of course, this also happens when running any application, the startup time is really long.
