- xterms and a jet, plus a few other clients, on my 4/110.

- But I disagree.
-
- Do remember that "top" gets physical memory wildly wrong under SunOS 4,
- since "unused" pages are used to expand the various system caches.

- Well, it'll save a little. Running xnews with -nosunview will save a little
- too, as will putting
- /IncludeDemos? false def
- in your .startup.ps to eliminate the inital TNT load.

-
- This _is_ true, and each xterm ends up taking about a megabyte on a colour
- system, depending on fonts and size.

- We use Sabre-C here sometimes. Hey, I only have 20 MBytes of RAM and
- 25 MBytes of swap space, and the only time I've seen it filled up is when
- I was using Sabre-C and Devguide, and someone else had DevGuide and a few
- other windows up... although having my 6MByte mailbox loaded into memory
- doesn't help.
-
- No-one, I think, will argue that X11R5 gives generally much better performance
- than OpenWindows 3, at least as long as you don't use Kanji fonts.
- But if you use NeWS at all, run FrameMaker, or any of the imaging programs
- that use NeWS (or the games!) you'll want to stick with OpenWindows.
-
- It shouldn't use that much memory, there's something wrong somewhere.
