On local writes I get about 2.3MB/sec which > looks close to hard drive performance. please, if possible post your machine's hardware configuration, there are several tuning tips people never do that may be hindering performance if you can give me this information I may be able to help more... cpu, disk type, ram, etc... if you are using IDE disks, i recommed you try to change the "flags" parameter to 0xa0ffa0ff and see if that helps, this will enable DMA on your hardrives. -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
