Hi

Don't use glMapBuffer and glUnmapBuffer, rather create a direct NIO buffer and call glBufferSubData or glBufferData.

Keep in mind that retained mode (vertex arrays, VBOs, ...) is faster than immediate mode if and only if you don't have to draw a very few primitives, it depends on the hardware too.
