It shouldn't be surprising that an architecture where two servers have
to touch every request is going to be slower than an architecture
where a single server touches the content.  Your proxy server could be
slow because the back-end servers are slow, or simply because of the
extra work in being a proxy.  One way to speed things up, if your
content is cachable, is to cache stuff on the proxy.

But, in general, you haven't given us much to go on in trying to help
you other than saying "my server is slow".
