Without installing it and making people use it, you would get no
benefit.... unless someone upstream installed it as a transparent

To tell the truth, the results depend largely on your user base (what
they do in common and how many of them) and the size of your cache.
Generally speaking, if you have enough people using it (but not so many
to overwhelm the server), it makes enough difference that the users can
notice it is *faster* then not using it.
