"wineserver is a separate application, and there is a context switch for every
wineserver call. That's how it works."
I'm well aware of the function of wineserver.
It's not a matter of context switches, it's a matter of rescheduling interupts.
It doesn't happen when the memory load is under 1.8GB ( 8 threads ) > the
average amount of rescheduling interupts is then 281/s.
There seems to be a treshold regarding a 2GB limit > then the rescheduling
starts to spike to 2.29k/s ( I've observed situations with 10k/s rescheduling
effectivily halting the proccess to a crawl )
I've thoroughly investigated the issue, do not reject this long term issue
without testing.
This issue exists in both wine32 wine64 so just answering wine64 is in alpha is
not a valid answer
I can supply you with all the programs to generate this kind of load, ( as
there aren't that many ) > or just fire up the windows version of blender and
render a scene >
