Hi list, I've replaced my old mailserver with a quadcore xeon, 4gb RAM and LSILOGIC SAS Raid. With this step I switched bayes from DB_File to MySQL. Switchover was easygoing, and the CPU usage is 4 times lower with the new machine, but I can see a huge increase with iowait and the normal system load. When working on 3 mails at the same time %wa in top raises up to 30%!!! Shutting down amavisd-new reduce it to 0 - 4. I've checked everything: - amavis in ramdisk - bayes with db_file again - bayes with innodb or myisam - bayes completely off - turned off RBLs
Nothing leads me to success. I have a second MX set up exactly the same, great performance, but with one difference: The second MX uses software raid. With the new one, debian detects the raid so ne need to build one. I thought that would speed up things, but it seems to be the opposite. Any ideas how to track down the error (without reinstall with SW raid :) Thanks, Michael ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
