Benchmarking

[maximegmd]

It would be great if we had some benchmark code to see how expensive Buffers, Sockets, Connections and Filters are.

I was thinking of using https://github.com/iboB/picobench though I am not set, as long as it's header only and fairly simple to use.

I can work on this if no one is yet.

Would the following benchmarks suffice?

• Buffer
  • Create
  • Clone
  • Destroy
  • Sequential write (bits and bytes)
  • Sequential read (bits and bytes)
  • Index (Random read)
  • Compare
• Socket
  • Create
  • Bind
  • Destroy
  • Send
  • Receive
• Connection
  • Create
  • Connect
  • Process Packet
  • Process Negotiation
  • ICommunication
    • Send
• DHChachaFilter
  • Generate Keys
  • Encrypt
  • Decrypt

I was more thinking about packet/second and data processed/second so that would mean a send/recv combo running for a few seconds to see what kind of bandwidth we can get per second. Then a DHChachaFilter connection handshake loop and after that a packet processing loop.

Regarding buffers it could be interesting to benchmark the cost vs std::vector for example as they perform pretty much the same basic operations.

I don't think socket create/bind/destroy should be benchmarked they pretty much only do the basic syscalls.
