I've run Netscape concurrently with several shells and programs : > such as Matlab. : What version of Netscape? Go to a JavaScript page and let it sit there : for a while. People have reported not only noticeable slowdowns of their : machines, but even crashes of the supposedly uncrashable Unix (it has : memory protection; how could an app possibly crash it? How could the : Titanic sink?). Netscape 2.0. The closest I have ever had to a "crash" was a core dump; it simply shut down the task and went on its merry way. The only time that happened with Netscape 2 is when I didn't install it correctly. Netscape, being a precompiled app, requires certain files to be in certain locations. : > The only time I would need to set priorities is when I'm : > running a timing-sensitive process such as RealAudio. : The claim was these types of problems went away with PMT. Guess not. I said "would need to", not "had to". Big difference. RealAudio takes about 50% of processor power. If I valued a steady audio stream above everything else I'm doing, then I change the process priority. Otherwise, I let the OS do its job. : > Many of the MEs at school regularly run Netscape while waiting for a long : > ANSYS job to run. Most programs (like Netscape) spend most of their time : > waiting for input, be it user input or data from the net. : Are you absolutely sure that someone hasn't imposed a per-process limit on : the amount of VM a process is allowed to allocate? There is no difference : between an admin setting it and you setting it, in my eyes. A limit is a : limit. No limits that I can detect. I can drive the machine into swap with one process if I care to. I can also have 100% processor utilization with one process. The allocations are dynamic.
