We've gotta yank that data out of a Berkeley DB. Of course, maybe it is
sitting in a shared memory segment, or the OS cache, or whatever, but it
will take a bit of time.

That said: we *do* support etags which can optimize GET performance. And
depending on how you ask for the content, it can be *very* cacheable. In
particular, it is possible that checkouts can cache at a local [caching]
proxy, enabling the guy sitting next to you to fetch his checkout at LAN
speed.

And last, but not least, you could put a caching reverse proxy in front of
Subversion. That would seriously offload the server. And if some Smart Guys
wrote a post-commit script to issue an ICP request to that proxy, then you
could keep the proxy up to date on all the content.
