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
