Sorry, I should have said "2.4 with your previous patches was already better than 2.2". >There are new graphs but you'll have to come to my WiP at >linux.conf.au to see then ....

This was already the case, using a large chunk size. BTW, thanks for your work!! - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to [EMAIL PROTECTED]
