Hi! Ok, so I'm compiling, and I'd like to run a flight simulator.
Flightgear normally does 20fps on my system... kinda low but playable.
I have reniced make -j 5 fo kernel running. Scheduler gives 100% of
one of CPUs to Flightgear (good), but the smt sibling is used by the
compilation, and I'm down to 9 fps. Not good.
Even with single-threaded make, I have 10-13fps.
Is there way to learn which CPUs are SMT siblings?
Is there way to disable SMT during runtime?
Can I do something to improve Flightgear performance and still do
compilation?
Thanks,
Pavel
