I've spent all week working on performance. It started when Lukey
|
|
found a way to use git cat-file --buffer to make --all faster.
|
|
Once implemented, that turned out to be a 2x to 16x speedup in seek time.
|
|
|
|
I felt that same approach could probably also speed up other parts of
|
|
git-annex that use git cat-file, so spent another 4 days finding ways to do
|
|
that. Some of the ideas are not implemented yet, but I landed a 2x speedup
|
|
today, to all git-annex commands that seek annexed files to work on.
|
|
|
|
Oh and also there used to be a git-annex branch read cache, but it got
|
|
removed many years ago, and I forgot it had been removed. Which does not
|
|
lead to writing the fastest code. Bringing the cache back makes some things
|
|
another 20% faster.
