‘ Load Average ‘ is an age-old metric reported in various operating systems. It’s often assumed as a metric to indicate the CPU demand only. However, that is not the case. ‘Load Average’ not only indicates CPU demand, but also the I/O demand (i.e., network read/write, file read/write, disk read/write). To prove this theory, we conducted this simple case study.

I don’t generally do random analysis of strangers’ performance problems but the case sounded interesting so I thought I’d take a look. Freya shared an ETW trace of what was happening on her machine and I took a look using Windows Performance Analyzer (WPA).
