Benchmark tool for servers supporting memcache protocol.

Supports simultaneous benchmarking of multiple servers.
Allows comparing two memcache implementations:

  * https://github.com/bradfitz/gomemcache/tree/master/memcache (clientType=original)
  * https://github.com/valyala/ybc/tree/master/libs/go/memcache (clientType=new)

For clientType=original the following sysctl may be useful:

  # sysctl -w net.ipv4.tcp_tw_recycle=1
