As the author, I totally agree. Especially for the deduplication benchmark there are so many variables that affect it that is definitely is worth restating.

That being said, I am quite confident the results are accurate and don't mind other people running their own tests.

Question: did you unmount/mount the source filesystem between tests? When the size of data is less than RAM you are measuring cache speed, not so much disk speed. (And yes I realize that you have SSDs.)

source filesystem was also ramfs for these.

This happens organically. If there is a benchmark the author doesn't use, then they won't be able to improve bupstash's performance on it.

The old saying is "you manage what you measure"

This is true, a few months ago bupstash was half the speed of restic for 'put' operations, because of my benchmarking efforts It is now faster.

I did have the benefit of being able to publish my benchmarks at the time of my choosing.
