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.

The network: - improves much for ping (ethernet drivers are patched https://marc.info/?l=linux-netdev&m=150654466102277&w=2) - becomes _worse_ for 1B, 1472B TCP pings - becomes better for 4K TCP pings The time for ZEO and NEO/* imrpoves by 100-200μs. It has to be understood what happens with TCP and then maybe other timings will improve more.

200μs of NEO/go without sha1 case is still questionable: T(transmit request) = 10μs (deco rx throttle) + t(link-tx-request) T(transmit answer) = 10μs·4.5 (~ 4.5 KB answer for 4K ZData) + teco.rx-delay (= 3μs ?) || vv T(link) ~= 60μs T(teco-local,no-sha1,NEO/go) was ~= 100μs (see time-sep17-teco.txt) T(deco-local,no-sha1,NEO/go) was ~= 20μs (see time-sep17-deco.txt) || vv T(teco-deco,no-sha1,NEO/go) = 100μs/2 + 20μs/2 = 60μs ? if so RTT(getobject) should be 60+60 = 120μs but we have 200μs.

Something is wrong with the network: ping latency is 110μs but go-go time is ~ 360μs which is not the same as 110 + 100 (go-go time on teco; on deco it is 30 and it should be even less: 100/2 + 30/2). Will investigate.
