Dogs, Rush hour traffic, and the history of storage I/O benchmarking–Part 2
Part one of "History of storage I/O Benchmarking" attempted to demonstrate how Synthetic Benchmarks on their own simply cannot generate or measure storage performance in a meaningful way. Emulating real workloads seems like such a simple matter to solve, but in truth it is a complex problem involving technical, and non-technical challenges. Assessing workload characteristics…

Twenty years ago, Administrators who tested system performance usually did little more than run a simple CPU benchmark to see how much faster a 50MHz system was than a 25 MHz system. Rarely did testing go beyond this. Nostalgia aside, it…
