I know that's tongue-in-cheek, but it's a bit too pessimistic. I'm a capacity planner, and CP is done strictly using time units (service and wait times vs load, to be pedantic), and doesn't care that something is virtualized at the resource level. It still takes time to do work, and so is predictable. Alas, what it does do is make it hard to figure out where the resource came from. I'd say that virtualization is just an obfuscation function (;-)) --dave [We now return you to your regularly scheduled observability discussion] _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
