[REQ] Hardware / SSE based MD5 operations
Last modified: 2017-10-12 11:31:40 UTC
I made some performance tests and ses that rsync can be a bottleneck while it is calculating hashes of basis files (not a surprise).
For example, while I can read a big test file directly from the storage at 300 MB/s, rsync checksums it at about 200 MB/s.
Thus impact of calculating hashes for big files can be quite important (some minutes for files of several hundreds of GB).
Then, what about MD5 implementation based on SSE ?
Do you think we would have a performance improvement ?
Thank you !
