Multiple shaders: how to deal with attributes?

Hello,
I was wondering which are the best practices (resulting in best performance) when using multiple shaders. The approach I would use at the moment is:
init:

• create and populate index buffer, vertex buffer, normal buffer, …
• compile and link glsl program

draw:

• use the glsl program
• query attribute locations for vertex, normal, …
• bind buffers, set and enable the attributes
• query all uniform locations and set corresponding data
• glDrawElements

Is there a better approach than re-querying all locations at each draw iteration?
Thanks!

Rather than querying locations at each render, you can store the locations for all the attributes/uniforms at the initialization then during render just use the stored locations of attrib./uniforms.

Mh indeed, makes sense. Thanks!
