being colocated dosent mean anything if your infrastructure sucks. e.g. what switch(s) you use, which PHYs/transeivers are used, what NICs you use, what kind of cables (fiber/copper) and what kind of hw/sw stack you run on. You might be surprised there`s 10s of nanosecconds difference between a twinax 10Gb copper cable, 0.5M 10Gb SR fiber and a 2M 10Gb SR fiber cable... which does make a difference. The differences between different vendors of NICs.. etc etc. ...this aint no FB/Google/blah.1M.requests.a.minute datacenter - its the latency not the thoughput that matters.
