It's just occurred to me to question this kernel configuration option, which is under Processor Type and Features.
We used to have to choose from 100, 250 and 1000 Hz, but recently 300 Hz has been added, with the following Help text: ---- CONFIG_HZ_300: 300 Hz is a good compromise choice allowing server performance while also showing good interactive responsiveness even on SMP and NUMA systems and exactly dividing by both PAL and NTSC frame rates for video and multimedia work. ---- At first I followed the advice without thought, but on reflection it occurs to me to wonder about the truth of this statement. I suspect it's only true in North America, northern Japan and a few other places, where the public supply frequency is 60 Hz. In the rest of the world, with its 50 Hz, I think 250 would be a better choice. I also think it would be more accurate to say "dividing exactly into" than "by". Would anyone like to comment? -- Rgds Peter Humphrey Linux Counter 5290, Aug 93 -- [EMAIL PROTECTED] mailing list
