memoslap

memoslap is a load benchmark for memcached servers, slightly faster but with many less features than the memaslap benchmark included in libmemcached.

Features

memoslap only supports TCP transport and does not check the correctness of values. Unlike the memaslap benchmark it provides the possibility to close and open new connections during the benchmark based on a maximum number of operations per connection.

Usage
