I haven't looked at that site, but, ive found when I enter or exit portals, even tele, by lodestone or using tele tabs I (upon landing) lag like freeze for 30 seconds, ive not actually times this. but it has caused me issues when fighting aggressive creatures, like Bossing. Ill suffer half my health due to this. ive tried using computer cleaners (for hard drive) ive ran security checks, all fine. I know that when my player is around any Bots I lag a lot more often, kinda strange, but... that's what happens.
