You're saying you get 35 mega Bytes per second? That seems highly unlikely! I'm not disputing the fact that your script might improve performance, haven't tried it, but there's not a hard drive in existence, excluding specialty solid state drives and RAIDs, that can sustain 35MB/s (I'm assuming by Mb you meant Mega Bytes and not Mega bits, which is what Mb is generally used for?). Shoot, I don't even think the UDMA bus can acheive that? I believe it's theoretical maximum is 33MB/s. Whatever you're using to get this performance number isn't measuring your disk throughput but your cache performance. Of course, if you meant what you wrote and get 35 mega bits/sec I could believe that, although if the drive was getting 5Mb/s to start with it's time for a new drive! Try using hdparam -t -T /dev/<whatever> for a little better estimate. Gary -- Unsubscribe? mail -s unsubscribe [EMAIL PROTECTED] < /dev/null
