SOME high-end machines have poor latency. In some cases, some tinkering with hyperthreading and LAPIC options may improve it greatly. But, some machines have just been poor, with nobody having figured out how to improve it. 36 us may not be horrible for a machine with hardware stepping or servo interfaces. But, 36 us is not great for software stepping.
