Re: [PATCH 2/2] Implement a simple delta_base cache

Linus Torvalds [off-list ref] writes:

Here's the trivial patch to extend the caching to 1k entries if somebody 
cares. I don't know if the small added performance is worth it.

This largely would depend on the project, but if a blob that is
cached is 20kB each, a 1024-entry cache would grow to 20MB.  We
may need to introduce early eviction of cached objects with
total cache size limit, configurable per repository.
