For a start, you could try a newer version of Peekaboo - apparently v1.6 still supports Classic MacOS. It’s probably the best tool for the job. Reading through its docs, I am reminded that applications are able to tell MacOS how often they want the “idle” events, from “immediately” all the way through to “never”. Some applications say “immediately” when they don’t actually need that, and they’ll show up as 100% on Peekaboo - but later versions of Peekaboo are apparently able to override it. Audio applications are a special case; they tend to do a lot of things at interrupt time, since the response time of the standard event system is not guaranteed in the slightest (again, *cooperative* multitasking). I don’t know whether Peekaboo handles interrupt-time stuff at all. However, it should be possible to *specifically* measure interrupt time using a program which measures how often idle events are received, or which repeatedly runs a short benchmark. - Jonathan Morton -- -- ----- You received this message because you are a member of the Vintage Macs group.
