Question about plan performance

Hi All,

I’m still not very clear about the difference between each plan regarding app performance.

I’m now start on professional plan at US62/mo…whereas production plan at US445/mo. Professional plan with 2 collaborator is ok for me, what about when my app grow…which one is better in term of performance, keep on professional plan with 20 additional server, or upgrade to production plan…both option will cost more or less the same.
