There's some pretty good docs on the interwebs. I believe that some guys from RH did a pres @ the RH Summit this year - you might stumble on a copy of that as well.... I believe that one param that will help is "swappiness" - default is 60, tweaking it determines how the kernel deals with swapping pages in and out of memory. You'd prolly want it set at 100 whereas application guys want it at 0 so stuff never leaves memory. Not sure how it might apply to a million tiny files tho... _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
