      The next commit will add remeasurements with C-states disabled.

      X z6001: localhost timings, Cenabled, zwrk@1s · 7f785235
      Kirill Smelkov authored
      Remeasure with the same sattings as previous z6001 localhost with C-enabled (850bfb9d):
      
      Like on neo1 the data is more or less the same and in particular timings
      for either sql backend or python client or even neo/go vs go client are noisy.

      Comparing to Cenalbled run, even when there each zwrk was run for 10s,
      similarly to previous measure with Cstates disabled (f40c8b4b) it shows
      clear improvement:

      not to mention that zhash.{py,go}, for which runtime was not changed,
      are also improved like it was in f40c8b4b, thus confirming timings from

      Compared to zwrk@1s (previous commit) the changes are in within, or
      close to be in within, noise and in particular it does not help for
      -zwrk.go timings like it did with Cstates disabled (f40c8b4b).

      X neo1: localhost timings, Cenabled, zwrk was running for 1s at each iteration · 4cbd62f7
      Kirill Smelkov authored
      Remeasure with same settings as previous neo1 localhost with C-enabled (9644774a):
      
      The data is more or less the same and in particular timings for either
      sql backend or python client are noisy.

      Disabling C states helps serial cases for zeo/py and neo/py/sqlite and
      both serial and parallel cases for neo/py/sql. For neo/py/sql it also
      denoises the timing.

      however it strangely shows that serial zeo-zhash.go latency improved
      126µs -> 112µs and serial zeo-zwrk.go latency got worse 110µs -> 125µs,
      so probably it is all noise and I will remeasure.
      
      Otherwise no significant change.

      Compared to yesterday shows relatively no significant change, though
      some benchmarks, like on neo1 & z6001, are itself noisy.
      
      Disk, like on neo1 is not stable from run to run (though it still shows

      Compared to yesterday shows relatively no significant change, though
      some benchmarks, like on neo1, are itself noisy.
      
      disk/randread/direct/4K-avg changes by 55%, probably showing we should
      be taking into account mdev(=std) ioping gives us, not only averaging
      the average it prints.
