Note that reading off the disk itself is often not the problem -- given
enough RAM, the OS will automatically have files cached most of the time.

More likely to be a significant cost is repeated parsing of those
templates... caching the parsed objects in python can help there, or even
storing pickles of stored templates and reading them in with cPickle might
help in some circumstances (or might be worse...).

In short, if your app isn't fast enough, profile to find the bottleneck.
Until then, speculation is mostly futile, and probably wrong.  The advantage
of python is you can have a working app much much sooner than with e.g. C,
which gives you much more time to properly profile for bottlenecks and think
of ways to overcome them.
