Well the pdf of changes was over 17 pages, so if you want you can read that.
Some kind of summary can be found here:
http://www.petri.co.il/changes-windows- … bugfix.htmBasicly it means:
Security updates
Stability updates
new or improved options
Performance
As you are only interested in performance, I can tell you that
* they claim that copying files on the same disk will go 50% faster, while to a different disk it was something like 20%-30%
* Hibernate and coming out of it will go faster
* Networks will improve, as will their file transfer rate.
* Some very annoying delays between activating an event and before it applies will be decreased or almost gone.
Sorry for not being in detail but it has been a few months since I read the changelog.
Go find the full pdf if you want to know it all.
