Upgrading macbook pro to mavericks - performance question
The question is, will Mavericks operate faster than Mountain Lion on my MacBook ? Will my hardware be able to run 10.9 efficiently ?


Yes. Mavericks has the same system requirements as Mountain Lion, but offers huge gains in energy efficiency, memory management, graphics performance, etc. And it's free!

If you're already in the process of moving over to Mountain Lion, I can't think of any reason not to jump directly to Mavericks instead.
