The iozone performs 10 operations: read, write, re-read, re-write, read backwards, read strided, fread, fwrite, random read, pread. Can anyone explain to me a little more than what their names imply or give me some references? Any help is appreciated. -Zhihui To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
