[...] I regularly test native Linux games on CFS, and they all behave well. While waiting for more detailed data from Kasper i was looking for atypical stuff in Kasper's description about what his workload involves, and what looked a bit atypical was that Kasper's workload also involved gaming under Wine: > > > my test subjects are quake(s), world of warcraft via wine, unreal > > > tournament 2004. [...] and Wine is a more complex server/client scenario instead of a single (and simple) standalone Quake3 binary that the Linux binary does. So it looked more interesting from a scheduler workload (and scheduler regression) POV. In any case i'll need more info from Kasper. Ingo
