Our current server is _just barely_ keeping up with our current usage.
However, that is not really sufficient.

1)Our pidgin.im webpage is currently a static cache of the "actual"
webpage, this makes it harder to make it fully functional.  Pointing it
at the "actual" webpage costs more in cpu & ram.

2)trac is still quite an expensive process, despite using lighttpd,
requiring regular monitoring to prevent it from going crazy.  Further
more, I believe we still have it partially disabled, for things like the
API viewing

3)our commit emails are broken.  My understanding is that the easiest
way to fix this would be to create a read-only mtn database for trac &
mail, to prevent locking conflicts. This requires more cpu.

4)we have talked about setting up a second mtn dbase for use by
translators, to give them commit access somewhere, but not the main
repository (since we cannot do access controls).  This requires more
cpu.

I am not strongly convinced that we are I/O bound, watching the munin
graphs that Nathan set up.  I think we are in fact CPU bound & RAM
bound.
