Will Mountain Lion offer performance improvements?

Sangdushi said:

is there any under the hood stuff being offered? I tried looking for it on the official mountain lion page on apple's site but it seems it's all extra applications and iCloud integration type stuff.

I have a 2011 MBA 13" with 128gb that I'm happy running lion on. will mountain lion offer any improvements or will it just be bloatware (at least for me)?

The trend of discussions in the ML forum seems to be that ML is a little bit snappier than Lion.

I would check out the ML forum for more info: https://forums.macrumors.com/forums/155/

They will probably have done some performance work, but its not really a selling point in most consumers eyes (unfortunately).

I suspect Apple does at least some performance work in every release, even though some releases come out a lot better than others.

There are so many variables on a desktop operating system like Mac OS X or Windows. Whether its "faster" or "slower" will likely come down to your specific hardware and software configuration.

air play is really the only feature that means a lot to me with ML

I think in anandtech's review he mentioned the rMBP gets higher frame rate performance in ML over Lion. There are numbers, I think nearly 8-10fps. So looks like there will be room for improvement in performance.
