I've tried many different workloads, kernel compile (normal -j4), extreme kernel compile (-j20) and Browsing/Open Office. GLXGears, Briquolo and enemy-territory work relly well under these loads. I just tried another test with "nice make -j20" and I see latency blips while gaming. SD did not have this. Latencies with nice are _worse_ than latencies without nice on my system. Playing with sched_load_smoothing does not change anything.
