Difference between the available splitters

[josef]

Maybe you find some information in this thread:

Low read performance per distinct hashing process

FWIW fixed splitters are not ideal if you have files that are partially modified as they don’t perform content-based splitting. So if you have a large video file (say 10 GB) and add one byte somewhere at the beginning (for example by changing embedded text metadata), fixed splitter will need to reupload 10 GB. content-based splitters (buzhash and rabin karp) will detect the change and typically only need to upload one or two chunks (<10MB total). Fixed splitter will be much faster, though.

Best seems to be the one with the lowest timespan.
Not sure why you see 0ms on all FIXED splitters though.
