It's been a while since I've played EVE, but one of the issues even since the beta was that certain systems were laggy. Jita springs to mind.
To combat it as much as possible the EVE team have used some cool and interesting tech over the years, but earlier today they announced what might be the biggest change in their hardware (that I've noticed). Being a massive nerd it's an interesting read, especially with further promises on more information. Whilst CCP are generally quite open it's great to see them continuing - which for a MMO is mightily unusual.
