java - What will be heap structure when Xmx is 2048m , MaxNewSize=64m and NewRatio=2 -

-

itemprop = "text">

My Java application is 2048m in Xmx, MaxNewSize = 64m and NewRatio = 2, I think the stack structure when all the parts

Young (64m) + Old (128m) + Easy Memory for the Permanent Generation Area

I think we are Hep Memory Is not using efficiently because more than 1.8 GB has been allocated for permanent generation.

Is that right? Or will it not be a heap structure?
