clutter batching

[salmokar james <salmokarjames gmail com>]

Hello,

While running the ./test-state test within clutter, and exporting COGL_DEBUG=batching , i am getting a lot of "len=1" output..

but within this bulk of "len=1" i also get this once in a while..

journal len = 24

clip stack batch len = 24

 vbo offset batch len =24

and some times len = 48 , 72 etc..

so does that mean that batching is not being performed efficiently(or at all) because majority of the times the len =1?

and why the len varies from 1 to 24 to 72 once in a while? what does this actually mean? and is this test case suitable for batching..?

I am new to clutter development and help and explanation would benefit.

Thanks,

Kind regards,

Salmokar.
