I have never considered the size of the repository in bytes that relevant
to performance, and other than the case of full text caches, I do not see
how it could matter.

For me, a realistic environment uses the Apache server and probably has at
least a few hundred repositories all of which are being used. For our
larger users it would be thousands of active repositories. Some of them
might be tens or hundreds of GB, but many of them are likely just a few
hundred MB.

I do not know what goes in the cache, but my assumption is that this sort
of environment would not lend itself well to caching of any kind. We
currently use whatever is the default.
