My first instinct would be what's already been said, things are probably running in the background or something. xD
You can try pipelining in Firefox if that's what you normally use (though finding an actual problem would be better).
Alright, so none of that seems to be the problem unless your RAM is total shit (I run upwards of 1GB in Chrome, haha)
Sorry, not sure what else would affect only Neo unless it's on their side, but I haven't had problems. :\
