checksum algorithm

Postby haer22 » Mon May 02, 2016 10:24 am

Whereas the new algos sha512, skein, edonr are so much faster than sha256 (50-350%), how much faster than fletcher4 are they?

The underlying question is: should we do
Code: Select all
zfs set checksum=edonr tank
?

Sorry to revive an old thread... but did anyone have an answer to this? I'm starting out fresh and would like to know if I should specify one of these new algorithms or just go with the default fletcher4. What I'm reading is that edonr is faster than skein but I don't know compared to fletcher4. I'm not interested in dedup, just getting a fast pool. Also, were there some issues with edonr? A fellow posted a few years ago not to use it but that's all the negative press I saw.
