The problem doesn't appear to be transfer time, but rather render 
time.  The link for data transfer only takes a couple of seconds, the rest 
of the time is spent figuring out how to display it.  One of the processors 
pegs to 100% during this.  Since turn off javascript cuts the time to 10% 
to 20% of the time with javascript on it looks like they are doing a lot of 
unnecessary fooling around with the display.  I expect you are using a 
faster processor for browsing then I am. Unfortunately Philips appears to 
have one of the sites that cripples itself when javascript is turned off, 
for no good reason that I can see.

The pdf download is, I think, an unrelated issue that I will try to track 
down as I get some time.
