Faster way to serve up simple requests?

[Jeevan _]

I have an extremely simple page that basically takes one value passed
as a get, fetches that key from memcached and serves the result as a
page (the pages are less than 10KB each). There's basically no
processing involved and it's a page that gets hit numerous times per
second.

Right now I'm using Apache + PHP + mcache (the PHP extension) to do
this simple fetch-from-memcached-and-serve routine but it seems
extremely wasteful to use apache and php for such a small, simple
task.

My question is: are there any smaller (less resource consuming)
programs out there that can perform this task?
