does it have different of the Subscription Pro and Business,i mean the load speed as image or others.or it just have different in Security defense？
Paid plans to get more Image Optimization features (Polish and Mirage). But the speed itself for a cached file will be the same on any plan. The only difference may be that free plan domains may get routed through a different datacenter if the closest one is very busy.
A full description of plan differences are here:
im the Pro plan 20$/per month now,does it have different with the 200$/per month of the speed?
Iit might mean faster load times if the user’s closest data center is under heavy load, but it’s not going to be noticable in most situations.
