Thats a very good point. I thought about using 32bit adds when writing the copy and checksum routine, but came to the conclusion that it wouldn't go any faster than one using addes. The checksum only routine was the same loop without the stores. We rarely use csum_partial now we have copy and checksum to and from user now, but I'll take a look at speeding it up in a follow on patch. Thanks!
