Norm and Chunky: On 2.2 kernels, I edit /usr/src/linux/include/asm-i386/param.h I usually change the #define HZ to 1000
I also edit the BogoMIPS printk() line in /usr/src/linux/init/main.c calibrate_delay() to print out the HZ so that a look at dmesg will tell me what time-slice a disk is running. I also recompile all modules - anything that might use jiffys.
