Oh and if you're playing while an event is on where people are going into Cyro to do dailies, etc, don't expect to have much luck with avoiding lag, we're usually stuck with it when events are on until they're done.
Apparently extra resources are directed to help with pvp lag but I've never personally experienced pvp lag decreasing when an event has been on. That might be because I've been away for a year though and things have changed a bit since then.
