This is great! However, do you have access to a big-endian CPU? I'm
not sure how relevant this still is but I've read at some point that
xxhash might have produced different (reverse?) hashes on different
endian CPUs. It may be prudent to acutally test if that is the case
with this implementation o
That's excellent news!

"The distro" is a bit vague for a t
Back in the spring, we started using rsync for a disk to disk backup
system maintaining close to 10PB of data. I am not here to debate the
issue of what is the right tool but only to discuss what we found to be
