Thanks for the information and doing so much testing. I see you used misc. VPSes - how can you know they provide consistent CPU and I/O performance, so your benchmark...

IIRC, we already have some notes in the docs that speed advantages of misc. algorithms depend on the CPU capabilities. But, as you have experienced, this is sometimes a bit...

Had a look and also re-grouped the lines, removed some less relevant ones, maybe it is useful if someone else looks at this: ``` Program under test Compressed size (bytes)...

@jdchristensen it has to compute the id-hash in any case and if blake2b is faster than sha256 (which is rather slow if computed purely in sw), that might be the...

One idea to make `borg extract` faster (in some cases): #1678

@safinaskar sure, some sort of files, like disk image files can contain huge amounts of all-zero chunks (in the optimal case as sparse areas, but also as on-disk zeros) and...

``` - Input data should be already in OS cache (i. e. one need to execute cat input-data > /dev/null before testing) - I dropped caches using sync; echo 3...
