I would strongly recommend you to do what Darksumone suggested.
Basically...
1. Look for a realm associated with the Boston data center; the link below will provide a list of realms in the East Coast governed by the Boston data center:
US realm list by datacenter - WoWWiki - Your guide to the World of Warcraft
2. Visit speedtest.com to do an ISP speed/latency test and pick the realm with the lowest latency
3. Create an alt on that realm to actually gauge your latency and to survey what the realm is like socially and economically. The wowwiki website does a really good job of providing an overview of each realm in term of populations, guilds, and progressions.
4. Do the character transfer when you find something tailoring to your need.
Regards and good luck.
