My S3 X server is currently at about 7.5MB, the usual pile of daemons (system, internet and NFS) chew up <1MB each, 16 xvts (like xterm but a little more lightweight) at 0.4MB each, the shells or rlogins/telnets running in each xvt, two xrns, an NNTP daemon, and all of the X stuff is running under tvtwm. I normally have a Mosaic running as well, which chomps down another couple of MB, and xv, when I run it, is a real pig. It runs fairly well in 12MB of RAM; I started out in 8MB, but that was pretty painful. The swap space is spread across two disks. I started out planning 16MB of RAM and guesstimated swap at (guess what!) 2xRAM. That was just too low, and when I added my second disk (850MB Connor IDE $209 at Fry's, now $195 there) I added ~64MB more swap. One of the things that complicates any analysis is peak usage, which is hard to track and measure. For example, I run UUCP and take a small news feed (C News). If I run bumping up against my virtual memory limit (like I was at just 32MB swap) the various processes kicked off by the UUCP subsystem would fail. I lost mail due to procmail running out of space while I was running xv, for example. Now I've got plenty of headroom and space for future growth. -- Scott Hazen Mueller | scott@zorch.SF-Bay.ORG or tandem!zorch!scott
