My first impression of commit [[!commit a0758bdd1002e798f62353efa725ac2972589b96]] with the cost model
is quite positive as I'm the one with multigigabyte annexed files in his otherwise rather small (by number of files)
repo and thus I'm affected by the limitations of the filter-process method which pipes all the content of annexed
files from git to git-annex. Compared to commit [[!commit 837025b14f523f9180f82d0cced1e53a8a9b94de]], which frankly
for me was unusable in this particular repo with `filter.annex.process` set, the new version behaves rather nicely
in that a simple test of `time git checkout git-annex` followed by
`time git checkout 'adjusted/master(hidemissing-unlocked)'` turns out to be faster than using an unoptimised version
(=8.20211028) without the long-running `filter-process` functionality. Obviously, it's only the first stage,
i.e. checking out the git-annex branch, that becomes faster by over 50 percentage points but I'll take any improvement
in my daily git-annex operations. :)
The timings I got are as follows.
* `git checkout git-annex`
- unoptimised 8.20211028 / w/o `filter-process`: 103s
- commit 837025b14 / w/ `filter-process` enabled: 36s
- commit 9d3ce224e / w/ `filter-process` enabled: 37s
* `git checkout 'adjusted/master(hidemissing-unlocked)'`
- unoptimised 8.20211028 / w/o `filter-process`: 49s
- commit 837025b14 / w/ `filter-process` enabled: 57 minutes (I had dropped a few files, in reality this would've taken even longer)
- commit 9d3ce224e / w/ `filter-process` enabled: 43s
This repo is on Windows (with annex.thin set) and locally has only 13 annexed files on this very drive but the files
cover some 870 gigabytes worth of system backup images so individual files are definitely on the larger side for
git-annex.
