This morning, we implemented a patch to the Communities platform. The patch resolved an issue where a dispatcher of static objects (.gif files, etc.) was creating a bottleneck, which resulted in a throttling of throughput. We also implemented front-end monitoring of the system, which simulates community members' experience and will notify us if page load times become too long. This will allow us to catch more quickly issues like that experienced early this morning. The new monitoring is in addition to the application monitoring that we already had in place since we went live.
So, the good news, and yes, we all need good news right now: Performance has been fast and steady the last hour. Please post in the Performance Feedback thread if you are experiencing performance problems.
I will report next some more detail on our plan for usability improvements.
