Spawn lag

I got a good server, and the spanw is a Huge castle, like 800.000 - 1.500.000 blocks.. idk but it make lag at the 80% of players, just in the Spawn Points, there're any method for fix it?

I have 1 Idea:
Destroy all the blocks from the bottom of the spawn, there are like 2.000.000 or more blocks just Stone, but it may work? Please help me, I don't want modify my spawn or do another...

 

Hello! The only solution I see is getting rid of some or upgrading your ram. Or possibly it could be a easily config fix

 

Do you by any chance have any mob spawners in that chunk?

If you do then that may cause the problem.

 

No, I don't have mob spanwers

Upgrading a ram of 32 GB?, nah hahaha
+ The problem isn't the Host, the problem is the PC
