Equally, it may represent inadequate performance compared with what performance a system is believed to be capable of delivering. I have examined this second definition before [1], studying how the library of CPU benchmarks published by the 7-Zip project [2] could be used to compare with observed CPU performance on my system. This month, I explore how to define baselines for I/O, including the storage and network subsystems.
