Concerning these half-static-half-dynamic files, I guess there's room
for improvement:

$ time curl --head josm.openstreetmap.de/maps

real	0m1.632s

sys	0m0.003s


This is over one second for shipping the header of an XML file which is
updated every once in a while [1].

What about re-generating this file on modification and shipping as fast
as possible (using Apache directly, Nginx or Varsnish). Maybe, having a
subdomain for static content might be worth a try (getting rid of
cookies, sessions etc.).

Cheers,
Simon
