If it had been better implemented there wouldn't _be_ as much swapping done. Of course, in order to do real time work you'd still have to be running a minimum of software, but that's Unix. That's one reason the NeXT is so ill-suited to video work. Of course, Stevie doesn't want you to think that. >I some how doubt that if half of the CPU is spent printing out >compiler error messages when you compile a program. Half was an exaggeration. However, I can guarantee to you that much less of my CPU is used by the GUI than the compiler than yours. Jobs' bright idea of devoting so much CPU to the GUI has crippled his machine. >When was the last time that you used a NeXT? The speed of Display >Postscript isn't a problem, and it does allow for more functionality. I can tell you the exact date, as a matter of fact. I stopped by our campus store after my first calc. test this semester. I played with one of the B&W 8MB/105MB boxes. It was admittedly faster than the old 030 NeXT that used to be there (when it was running). However, it wasn't any faster than my machine, and I'm sure you know what processor I have and what speed it's running by now. :) We have a NeXT on the net here. It doesn't get used much, but I logged into it the other day. It's pretty fast -- about even with one of the SPARC 1's we have here. The 1+'s (which I normally use) are a bit faster, though. I haven't dug out the benchmark code, yet. This is all perceived speed to the user. When you don't have to deal directly with NeXTStep it's a decent machine. > >-Mike Greg -- Greg Harp |"How I wish, how I wish you were here.
