The server hardware had been upgraded to dedicated i7 4790k 4.4ghz, 16mb ram and fast SSD running Windows Server 2012 R2
Internet connection was also upgraded today, not that Ark uses much bandwidth but just in case 😉
It might still lag for a few seconds while doing the world save each 15 minute and other Ark world cleanup stuff
Not really much we can do about that other than blaming the Ark devs ;-/
