I thought I'd add a data point to the discussion regarding excessive swapping causes by X... Jim Howard writes in response to this issue: of excessive paging by X: >But those differences are small, and they still don't explain the horrendous >swapping generated by X, unless the decision to swap is totally blind to >page sharing, which makes no sense. TO add an additional data point to the fray, I'm running the june snap of 2.0.5, 16M, 128M swap spread accross 3 disks (one IDE, two SCSI's) with the drive LED's extended to the outside of my case so I can see disk activity. I normally run X with 3 opened xterm's, the window manager, the normal daemons, getty's, etc. I begin to swap once I start the third "cc -pipe". I've learned not to "gmake -jN" with N > 3. With three cc'c going, there's some paging, but it's intermitent, and does not seem to impact throughput. Once I exceed three cc's, then I see the xterm's being swapped out and a lot of thrashing as I move the mouse into and out of the xterm windows. So, I see no excessive paging problem with 2.0.5 running X on my system. Of course, I only began using FreeBSD 6 months ago with 2.0, so I don't know if it ran X better with previous releases.
