This comes in handy especially when comparing multiple types of executors but also to just establish once and for all that we are faster than go.net.

Methods

2 variants:

• echo server timestamps itself and produces histograms

  • upsides: stats for multiple clients
  • downsides: either we share the histogram for go.net which causes contention, or we make one histogram per connection in both echo servers

• echo server just replies:

  • upsides: super simple, we really measure the efficiency of the IO executors here
  • downsides: when connecting to multiple clients, each client needs to keep its own histogram

Other stuff to test

• writing 8, 32, 64, 128, 256, 512, 1024, 2048, 4096 and 32KB

• keep track of number of messages
