We've been having performance issues and stability issues running Adobe Livecycle ES2 on T-series;hence we're doing a POC on M-series. This came after finding out that Adobe LC is not meant to take advantage of the T-series architecture which is more suited for multi-threaded applications. So, as of today our testing on the m-series is looking good.
My concern is, and we're planning of using reader extensions and rights management, is when we expose this to many users.
Is there anyone running on m-series with more than 1000 users and how is that performing?
