Thomas,
Given that gitweb (and more than a few other similar tools) doesn't
use FUSE and works on bare repositories I question why you think you'd
need (or want) to introduce the additional layer.

If your concern is caching, it should be implemented upon already
rendered / prepared objects whenever possible--frequently not a file
system level implementation. This is a design concern that has no
specific requirement whatsoever to do with FUSE (or for that matter,
with most of the VFS layer when accessing raw disk--as VFS itself is
highly optimized already).

I am not qualified to answer questions about FUSE use of the VFS cache.

I would strongly consider using a tool such as Varnish if you are
concerned about performance when serving static or semi-static content
(may it reside in a Git repo or elsewhere). The architectural concerns
of your web-app should probably guide your design in this sort of
direction anyway if it will be expected to sustain notable throughput
over time.

I hope that helps.

(If you want to discuss this further it would be worth considering if
your questions are Git questions or web-app design questions. The
latter should be taken elsewhere.)
