True Blue Environment- Slow Computer
Classic, aka True Blue Environment, tends to get a hiccup every now and then.
When it does, it tends to eat up all available CPU resources. To ‘fix’ it, you can force quit it in Activity Monitor or just restart it from the Classic preference.
Classic is a full OS. An OS that does not ‘play well with others’. It is taking as much as it can, but the main OS X kernel (Mach) is suppose to take back anything it needs to give to another program. Basically, Classic is considered ‘low priority’. If nothing else wants processor time, Classic will take it; but it something else DOES want it, Mach will force Classic to give it up. If Classic is running without any applications, it should use little or no resources. But, if a classic app is running it might take a bit, and often more than a similar OS X application, and especially if that application really, really wants attention (like a save or open dialogue), then Classic quickly will require all the resources it can.
