All I was trying to say is that their page appears to contain a LOT less HTML, for very nearly the same functionality. Each pprune page is around 200 kilobytes of data, most of which is not necessary.
It would not suprise me if having a careful look at how each pprune page is generated halved this, and that's worth a lot of server power and ISP bandwidth.
To be fair, most websites today use a huge amount of data, for what is actually displayed. When "the firm" is paying, one just throws a big server and lots of BW at it.
