Please reply to sparky@cs.kun.nl, since I'm not > on the list If your performance got much worse your stripe size is obviously to small. bonnie is using single file transaction so don't expect to be much faster than a single drive with this programm. The ncr driver is running fine - the newer sym driver seems to be slightly better but I asume that your controller is a plain 810 and not an 810A so it is not supported by the sym driver. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
