[Wine] dramatic slow diskperformance

[kenny82]

Hi all, 

I'm using Wine for a MotionCapturing Application (Qualisys). Although it's a quite recent application, it works well (I tried only data processing so far), but when I try to save a dataset (~180MB), it takes about 20 Minutes (!!) on my Computer. When I use it under VirtualBox (it does not run nicely there because of OpenGL), saving takes about 20 seconds.

When I look at "top", I see that "Qualisys.exe" takes about 80% CPU, and "wineserver" about 20% CPU. (I have 2 cores, so 200% would be the limit).

What's wrong? And how to fix it?

best, 
 Kenny
