This from the *excellent* paper at linuxdevices on latency
measurement. BeOS, eat your (cold dead) heart out:
2.4.17 with Andrew Morton's Low Latency patch:
maximum latency: 1.3ms
Mean: 0.0542797399957571ms
Standard Deviation: 0.025220506601371
96.66250% of samples < 0.1ms
99.21158% of samples < 0.2ms
99.99592% of samples < 0.5ms
99.99984% of samples < 0.7ms
99.99992% of samples < 1ms
100.00000% of samples < 1.4m
Yowza! I mean, I knew it was good - I didn't know it was *that* good!
Even better: this is *with* IDE drives under some level stress (but no
X Windows).
