I could not find a forum post about the RC yet so I decided to start my own.
I installed the update on our test system a few days ago and I must say there has been a huge improvement on the speed of APM. Going into the specific graphs and changing dates and time frames was always slow and somewhat cumbersome in APM but this seems to be as fast as the regular NPM module.
Only issue with the install was that it comes packaged with SQL express by default and has the option to install SQL selected as the default choice. Since I would assume most people already have APM/SQL installed and this is just an update I was surprised by this choice.
Other than that great work on an awesome update!
Our APM Beta/RC folks should have access to the APM beta forum. Let me know if you don't and I'll get someone to correct that oversight.
