Predicting Memcache Throughput using Simulation and Modeling

IEEE Symposium on Theory of Modeling and Simulation (TMS)

The current work introduces a method for predicting Memcached throughput on single-core and multi-core processors. The method is based on traces collected from a full system simulator running Memcached.

A series of microarchtectural simulators consume these traces and the results are used to produce a CPI model composed of a baseline issue rate, cache miss rates, and branch mispredictions rate.

Simple queueing models are used to produce throughput predictions with accuracy in the range of 8% to 17%.
