Summary: WinRAR's multithreading mode doesn't work correctly on
SMP system
Product: Wine
Version: CVS
Platform: Other
URL: http://rarlabs.com/download.htm
OS/Version: Linux
Status: UNCONFIRMED
Severity: major
Priority: P2
Component: wine-kernel
AssignedTo: wine-bugs at winehq.org
ReportedBy: t.artem at mailcity.com
I've recently upgraded to a dual core AMD Athlon 64 CPU and now I'm able to test
multithreading mode in WinRAR.
The raw data follows:
WinRAR single threading mode: Wine 614Kb/sec | WinXP 626Kb/sec
WinRAR multi threading mode: Wine 605Kb/sec | WinXP 1020Kb/sec
I have kernel vanilla 2.6.21 linux kernel with SMP support - 7-zip archiver
works correctly, i.e. when I enable multithreading 7-zip's performance almost
doubles.
One anomaly is visible when I enable multithreading mode in WinRAR/Wine: system
CPU usage becomes excessive and wineserver process eats too much CPU cycles.
