Description of issue

Ghasts Teleporting through Nether Portals cause significantly more lag than other Entities.
This should be a matter of vanilla

When a Ghast uses a portal, it causes a lag spike on the server.
It would be nice if Purpur had a configuration that prevented Ghasts from using portals, or had this lag fix patch.

Good. Purpur has the 'entities-can-use-portals' configuration, so I think it will be possible with a small modification to this patch.

Issue with Ghast's collision box size
Is it possible to modify the Ghast's collision box size by adding an option，to solve this vanilla lag problem
like this:

I want to disable the portal only for Ghast and not all entities.

Wouldn't it be possible to change it like below? (I don't know how to change git diff HEAD.)

I think the best solution is to add a configuration that skips the collision box size check if the entity moving through the portal is a Ghast.
