Kernel tweaks/patches to improve responsiveness?
Hello, I have a question about improving the GUI responsiveness and load time of Linux applications. I have an old computer, 300 MHz, 128MB RAM, 8MB graphics, slow hardrive, and it runs RH9 and KDE 3.1 tolerably well. I would like to see how fast I can get this thing to run, without upgrading hardware. I have no back-end processes that I really need to worry about, it's just a desktop. I recompiled the kernel, and I changed HZ=100 to HZ=1000 somewhere in the sources, sorry can't remember where. Anyway, it made no difference, although one person said it cut app load time by 1/5. Are there any other tweaks to the sources that really work? How about patches, such as the preemptive scheduler patch for Linux 2.5? (Where is this patch located?) Thanks for the help!
