Bogomips are meaningless. Bogomips are meaningless.
Bogomips are meaningless. Bogomips are meaningless.

someday I'm gonna talk Linus into doing this just for kicks:

--- linux/arch/i386/kernel/setup.c.orig
+++ linux/arch/i386/kernel/setup.c
@@@ asdfasdf
-sprintf(p, "bogomips:\t\t%lu.%02lu", loops_per_sec+2500/500000, etc.)
+sprintf(p, "bogomips:\t\tone-hundred-billion-million");
