There was no reason to be rude and patronizing. Much of this thread and the popular opinion of cookies are that they're bad and scary, but the reality doesn't match the hype. I wasn't attacking you, and you should have shown more respect.
My post was written to clarify the nature of cookies which are neither malicious nor dangerous. I accept that Quantserve may be a very slow server. My understanding is that Internet browsers either have a very small timeout on cookies, or else the page loads regardless of their delay - in the same way a web page will load while it waits for pictures or other media content to finish downloading.
"Send For: Any type of connection" means the cookie is delivered whether you are connected to Quantserve normally or encrypted. It does not mean it communicates with Quantserve regardless of where you are on the Internet.
Finally, the homepage of jeepforum has this file in the source: http://edge.quantserve.com/quant.js
(click the link to see the content of it). The cause of your problems will be something in the code, not the cookie itself. Look here for clues: Steve Sounders
your Internet activity sped up after you deleted your cookies, that tells me either your cache is set too large (either in file numbers or total size), or the majority of your Internet activity happens to bring you in regular contact with Quantserve, or you have a problem with JS (Noscript etc).
