Created attachment 65276 [details] hack
Here's a hack that allows you to restrict Wine processes to a subset of the available cores. You can pass a CPU mask through the WINECPUMASK environment variable:
$ WINECPUMASK=0xff wine ...
This will tie Wine processes (including wineserver) to the first 8 cores. It will also limit the number of reported cores to 8.
Wouldn't taskset/cpuset be simpler?
