That surely depends on the information source. For example
http://www.javaworld.com/javaworld/jw-02-1998/jw-02-jperf-p4.html shows that
it's not as bad.

Now I agree that the site I mention is probably a bit biased. (although they
clearly explain what they test) I had some other good sites, which compared C++
and Java (and it was not a java-only site) which came to the conclusion that the
newest version (1.4.x) is about 20% slower than comparable C++ code (compiled
with M$VC++, version unknown)

The page I posted above wants to set cookies. ;) But I don't think they're
really needed in order to view the page. So you should be safe. :)

Well, a cookie can only contain info they already have, because the cookie is
sent from the server to the client. If they only want to track my purchases,
they can check their webserver log.

Btw: I don't accept cookies which have a different URL than the site I
requested. And I don't accept permanent cookies. (although I don't consider that
a terrible problem either) Which leaves cookies coming from the current server
and which are deleted when I close my browser. The only use for that is to hold
session context. And for that a cookie is better suited than sticking the whole
%^&&^( in the URL as a get-parameter, or hidden form fields. So it seems I'm
less paranoid than you are. :))
