Max < 3x (nprefetch=8) in go-go case.

improves max 2x becase probably of go scheduler.

Compared to no C-states disabled (but RX delay = 0 as before) it improves:

Same as on oct4 - we just add C-states profiling. In particular TCP1472 and TCP4096 are awful.
C-states are not yet disabled.

Same as on oct04 but now we add C-states profile. C-states are not yet disabled.

~ the same as on oct04 only we add C-states profiling. C-states are not yet disabled.

py timings improve a bit - ~15-20μs per python part (i.e. ~30-40μs if
both client and server is in python).

go-go timings stays ~ the same.

Timings are ~same as on sep17 but now a lot more info about system is
added + C-stats profile. C-states are not yet disabled.

Like info-local but about any remote deployment.

Numbers stays the same; we just added more diagnostic to log.

for ZEO and NEO/py the time over network is ~ the same as the time over just IPC on z6001 !
for Go network makes it visible slower.

Probably C-states play a big role above.

Seems to be similar to localhost on z6001 and is a bit _faster_ for cases where
ther is interprocesses communication.

This is explained by the fact that intel_idle tend not to go to deeper sleep
states whenever system loadavg increases.

Seems to be similar to localhost on neo1.
