Feature, not a bug
Authored by: babbage on Nov 17, '01 04:25:54PM
I would think this isn't something specific to the Terminal.app. I remember when OSX was just coming out -- maybe even during the publc beta stage -- there were demos of it running Quicktime movies minimized in the Dock. I would assume that doing that sort of thing took a whole lot of work, as playing full speed video is fairly computationally intensive anyway, and then the system has to dynamically rescale that video to docked size on the fly -- and even more so when using the dock magnification feature.

You're noticing the problem with the Terminal, and maybe it does indeed lack any optimization that Quicktime & other applications might have for docked performance, but I would think that most applications will generate a performance hit when minimized to the dock this way.

The two solutions I can think of would be [a] to run long, non-interactive command line programs in the background (thus avoiding any strain on the Terminal, whether or not minimized), or more generally [b] to hide (cmd-h) applications rather than minimize them, thus avoiding the minimization that seems to be consuming all those CPU cycles.

Feature, not a bug
Authored by: bankmann@mac.com on Nov 28, '01 05:26:09AM

I just upgraded to 10.1.

I was running the CPU Monitor in the Dock when I noticed the load was constantly between 80% and 95%... On a G4 450/DP with 768MB RAM and about 80GB HD total, I found this worrying, since I was only running Eudora and the Terminal App, apart from CPU Monitor.

I was running top in the Terminal, and knowing this would consume _some_ CPU, I stopped it. No change. Terminating Terminal, though, did the trick.

Thing is, I got this load while Terminal wasn't minimized. I haven't checked after this, but you've given me something to think about...
