The beginner servers wipe every 3 months or so, the next wipe is scheduled sometime in late January. I currently play on a beginner server, #430 and it has plenty of space left for bases, just not along the coastline and the easy zones lol. The lag you're getting would be from the large amount of tamed dinos and the huge bases on normal servers, your lag should be better on a beginner server. I've also heard there are "Arkpocalypse" servers that wipe every month but I've never tried them so I'm not sure.
