I have the premption patch turned on. On a 192 MB PIII laptop running at 500 MHz I have two X sessions running, and have opened a zillion application windows on each, including over a dozen Netscape windows, some Mozilla's, a couple emacs's, a kernel compile, Staroffice. About every app I can immediately think of. I haven't tried malloc-ing a ton of memory, but this contrived real-world test works. Swap is at 238 MB. Lower than I would have expected, but that doesn't mean I know anything. Switching between X sessions just took near 10-seconds going, and only about 5-seconds coming back. Switching in Staroffice is painful, but generally the responsiveness feels quite nice. I like it. Thanks, -kb, the Kent who will be staying with 2.4.9-ac15, plus preemption patch, plus this patch--once he figures out how to close all those windows.
