I assume your getting slow connections to many different places so you 
know it's your end.  If you can hit someplace you know is unloaded (like 
work after hours) that may help troubleshoot.

Here are some things you can try to see what the problem is.

Use nslookup to check dns.  The first request may be slow, but repeating 
it should return quickly.

Use ping to see if any packets get dropped.

Use traceroute to see if there are any very slow hops.  If there are 
some close to you, it's likely to be your ISP.

Use ethereal or tcpdump to look at the packets.  A lot of 
retransmissions indicate network problems.

I'm no expert at network analysis, but maybe you'll find something that 
jumps out at you.
