You seem to assume that if you see a round trip time of .27 seconds,
that then PyPI could only do 3 requests per second. That is not so.
I just logged onto www.python.org (a machine that is close to
cheeseshop.python.org), and called this function:
>>> s=xmlrpclib.ServerProxy("http://cheeseshop.python.org/pypi";)
>>> def f():
... start=time.time()
... for i in range(1000):s.package_releases('setuptools')
... return time.time()-start
...
>>> f()
7.6247878074645996
So it can currently do 130 XML-RPC requests per second, to
a single client. Inverting it, a request takes 0.0076s,
which is a lot less than 0.27s.
