Hello Joey,
So I have another idea to speed up git annex sync --content --all. As far as I understand, the first pass with --all (walking the worktree) is just to make preferred content expressions which include paths (and lackingcopies=) happy. Now, if the preferred content expression of the local repo and of none of the remotes contain paths, that first pass can be skipped.
I did some benchmarking by replacing the following in seekSyncContent:
Just WantAllKeys -> Just <$> genBloomFilter (seekworktree mvar (WorkTreeItems []))
with:
Just WantAllKeys -> pure Nothing
and it led to a 2x speedup (with warm cache):
before:
real 0m41.186s
after:
real 0m22.182s
This repo has 25641 keys and all of them are in the worktree too.
