2.15. Use Vertex Buffer Objects

A Vertex Buffer Object (VBO) is a data storage mechanism that enables an application to store and manipulate data in GPU memory. VBOs provide a large reduction in overhead so can provide a considerable performance increase.

If you send data to the GPU every frame it is copied whether it has changed or not. Using VBOs avoids these copies because storing data in the GPU memory means no copies are required.
