With the Quasar platform.
Bigger fights are coming to Eve Online, as CCP Games detailed a new technology platform called Quasar. Quasar moves in-game systems like skill plans to another database for the first time. The goal here is apparently to allow the main server Tranquility to handle more actions at a faster pace, and the result being bigger battles that are faster and smoother. How many more records might Eve Online set? All of them. All of the records.
