What kernel are you running? I don't have it that bad, with 2.6.13, but it's definately slower than earlier 2.6 kernels. raid0 performance used to be very good. raid1 has always sucked (reads no faster than a single drive). /dev/md0: Timing buffered disk reads: 322 MB in 3.01 seconds = 107.06 MB/sec /dev/sda: Timing buffered disk reads: 216 MB in 3.03 seconds = 71.37 MB/sec /dev/sdb: Timing buffered disk reads: 218 MB in 3.01 seconds = 72.53 MB/sec -- Tom Vier <[EMAIL PROTECTED]> DSA Key ID 0x15741ECE -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
