2.0 Changes mainly interested in speed improvements if any

I haven't seen anything indicating that Opencart 2.0 has speed improvements but that only means I have not seen them. They might exist. If they do, can someone point me to any info on speed improvement added to 2.0?

Thank you,

Mike

Hi,
I talk about the speed improvement a little bit using gtmetrix. You can watch my video. Let me know! Thanks.
