I ran into some problems with my PPC 7100: It's damn slooooow.
I use AV graphics, 24 MB of RAM. Macromedia Director updates graphics
at nearly 30% of regular speed and while using my comm ports changing
between applications (e.g. Netscape for PPC to some other) by
mouseclick is really time consuming (2-6 secs sometimes). I never
really noticed that because I used a old MacII before ;-) but I had
the chance to compare to another PPC 7100 and I was pretty surprised.
I checked drive fragmentation and RAM settings for the programs. I am
not too firm with operating systems, and I would appreciate if someone
can give me a hint how to diagnose the problem.
