We could spend a lot of time perfecting the\nright set of cache misses to reflect those costs.\n\nOr, we could make a per-cpu spinlock that gets held while we\u0027re doing\nthe matrix math.  This is a pretty blunt hammer but it accurately\nreflects the impact of preemption on our workloads.\n\nSigned-off-by: Chris Mason \u003cclm@fb.com\u003e\n"

Instead of focusing on wakeup latency, this\ncalculates the latency from the time the request is queued up for a\nworker to the time the worker finishes the request.\n\nTo help normalize the results, we subtract the cputime (--cputime) of\neach request from the latency number, so we end up with the extra time\nwe spent waiting between when the request was queued to the time we\ncompleted it.\n\nTo normalize things a little more, a p99 summary is given where we\ndivide this extra latency by the cputime.  For example, with the default\ncputime of 30ms, if the delay is 15ms, we\u0027d print a latency of 50% of\nthe cputime.\n\nThe real advantage for -R is to use it along with --auto to process a range\nof workloads all at once.\n\nschbench -m 2 -t 23 -R 1 -a -r 10\n\nUsing -R 1 tells it to guess a good starting point, and keep bumping the\nRPS until the delay gets too long.\n\nSigned-off-by: Chris Mason \u003cclm@fb.com\u003e\n"
