MySQL Proxy: Reducing Latency

To test if we make progress I use mysqlslap in its most basic form:

$ mysqlslap --host=127.0.0.1 --port=4040 \
  --create-schema=mysqlslap --iterations=1000 --concurrency=10

which only connects and closes the connection again.

The run-time over 10.000 connects is

proxy, no cache, lua_gc()  11.553s
proxy, cache, lua_gc()      7.065s
proxy, cache, no lua_gc()   6.458s
