I have a Lion with 4 666mhz B3 stepping cpus and 4GB ram running Debian unstable with kernel 2.4.18 and the 020410 ia64 patch (I have the same problem with 2.4.9-itanium-smp from the archive).
I have a program that reads large files in increments of 81920 blocks. After about 9600 read calls I get about a dozen reads that take about 3 seconds each. Does anyone have any ideas as to a cause/solution? (I have 4 other threads working/possibly writing output at the same time, although in this case it's only 1 of them would be active at the same time). I am also running a program that callocs almost all my ram to make sure none of the file is cached. I can provide more info if necessary. Here is a partial log I made (read#/time in seconds): 9597 2.823812008 9598 0.009531000 9599 0.000220000 9600 0.010351000 9601 0.014768000 9602 0.000213000 9603 2.910599947 9604 0.009694000 9605 0.000193000 9606 0.014762000 9607 0.000193000 9608 0.009892000 9609 2.869304895 9610 0.000717000 9611 0.014134000 9612 0.010046000 9613 0.000200000 9614 0.009780000 9615 0.000200000 9616 2.974085093 Thanks for your help. -- Rick ([EMAIL PROTECTED]) http://dxr3.sourceforge.net I think the slogan of the fansubbers puts it best: "Cheaper than crack, and lots more fun." -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
