Bogomips are used for micro timings in some device drivers. I don't think they are used for any other purpose. Mostly this is for devices with funny timing characteristics such as not accepting a second command for a short period after getting a first command.
The channel architecture of the mainframe isolates drivers from this kind of thing, so bogomips should not be used on the mainframe. -----Original Message----- From: Jim Sibley [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 28, 2003 9:01 AM To: [EMAIL PROTECTED] Subject: bogomips and vm guest performance I've noticed that if I start 10 or 12 VM linux guests at "the same time", after they are up the bogomips vary by almost an order of magnitude (1 guest may have 900 bogomips, another 100). Since bogomips are used for timinig purposes within Linux, does the difference affect the relative performance of the various guests? (If you stagger the start, in my case, 1 second between xautolog's, the bogomips between guests are closer). ===== Jim Sibley Implementor of Linux on zSeries in the beautiful Silicon Valley "Computer are useless.They can only give answers."
