Pmc performance monitoring counters
WebPMC == Performance Monitoring Counters, aka CPU Performance Counters (CPC), Performance Instrumentation Counters (PICs), and more. These are processor hardware counters that are read via programmable registers on each CPU. The availability of these counters is dependent on the processor type. See pmc(3) and pmcstat(8).
