An order of magnitude too slow in my view. I was initially seeing speeds like this during my recent reshape, but got it up to around 30MBps. I can't recall exactly what I did to get it running better - it was the equivalent of giving the television a good whack - but I seem to recall that increasing the md stripe cache size helped the most. I don't currently have access to my work computer where the command history lives, so this is all I have for now. If I find anything more to try, I'll chime in. -- Kristleifur -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
