For the first time ever with postmark, I saw errors like this: Error: cannot open '34878' for writing Error: cannot open '34879' for writing .Error: Cannot delete '31484' .Error: cannot open '31483' for reading Error: Cannot delete '30648' .Error: cannot open '31483' for reading .Error: Cannot delete '30352' Done Deleting files...Error: Cannot delete '30352' Error: Cannot delete '30353' Error: Cannot delete '30648' Error: Cannot delete '31486' Error: Cannot delete '32103' I'm guessing that the async filesystem under Linux just couldn't keep up. I'm hoping that this hasn't permanently trashed that filesystem. ;-) I also noticed that system CPU usage was *much* higher under Linux than it was under FreeBSD. I saw peaks of 97% utilization in system time, and I'm going to re-run these tests under the bash "time" command to see if I can get some averages of system versus user mode usage, etc.... Anyway, the results I got were: Transactions per second: 97 KBytes Read per second: 230.58 KBytes Written per second: 418.22 The re-run of the second sequence with "time" is now underway. I've also got back initial results of running postmark on a similar Dell PowerEdge 1300, but this time one with two 450Mhz processors. Otherwise, it is configured pretty much identically, at least for the subsystems I'm testing so far. The filesystem is *not* mounted with softupdates. The results I got were: Transactions per second: 35 KBytes Read per second: 110.58 KBytes Written per second: 113.06 I'm re-running this command under bash "time" as well, and all future results to be reported will be likewise. I'm also going to go back and do the same for the tests I ran on the older PPro 200 machine with 128MB RAM. -- These are my opinions -- not to be taken as official Skynet policy ____________________________________________________________________ |o| Brad Knowles, <blk@skynet.be> Belgacom Skynet NV/SA |o| |o| Systems Architect, News & FTP Admin Rue Col.
