Why is this site so slow.  It can take as long a 5 minutes for a thread to open.  Trying to post a reply is getting to much of a hassle.

That would be a question for Jamie in the Feedback forum. It could just be the time of day your using the server, it responding well for me. If the problems all the time, check your system for spyware/malware/viruses.

 

Disconnect your modem, shut your computer off. Wait five minutes. It worked for me!

I've noticed the same thing, sometimes the cable modem seems to crawl, running a performance test from the internet yielded poor results. Shutting down the modem and restarting it increased performance greatly. (At least  temporarily)

I'm on a cable connection, the problem is this site. Other sites load fast when this one is slow.
