That's my problem, I can't remember where I found it on the web! I know it was back during the 8.0 days of Mandrake. I recall a post, that I thought was on one of the Mandrake lists, but I sure can't find it. The post pointed to an article about increasing the HZ size and how it improved response times for desktop users. It also stated that Redhat was doing this with their kernels, which is why their i386 seemed so snappy compared to Mandrake and Suse. The downside was something about timings being off for some tools because the items in /proc weren't aware that the HZ had been changed. It was my understanding with Redhat 9, they continued this practice of changing the HZ but also modified the tools that calculate the various things in /proc. I'm sorry I don't have more information, but I have long since given up finding the original article. It seems Google wants to return 50,000+ hits everytime I try and after a few hundred, I give up. If I ever find my hard copy, I'll type it back in to the list. Joeb p.s. It's also my understanding that the 2.5/2.6 kernel has increased this setting.
