Great to hear, thanks for giving it a try. io-stalls-6 helped most when you've got multiple devices and a streaming write to one was slowing down all the others. -7 added in a tweaked form of Andrea's elevator latency fixes, and they make a big difference when there's a lot of writes to the drive you're trying to read from. Hopefully we'll be able to hash out something suitable for 2.4.22-pre. -chris
