Multiplayer Character Moves At A Crawl

I'm not lagging or getting that 'rubberbanding' issue that I've heard so much about. Everything moves smoothly, it's responsive. Nevertheless my characters run at a positively leisurely pace. My character often trails so far behind the others players that by the time I get there, the fighting's already done. Is there some setting or ability that I'm missing so that my characters can actually, in terms of movement, keep up with everyone else?
