The focus of this release has been the performance. CR6 is by far one of the best performing MMS! MMS now can easily have 200 concurrent Announcement or IVR. Details here
One of the major issue was Buffer was created too frequently and not reused which caused frequent GC. Other issue was with Inband Dtmf detection which is based on Goertzel Algorithm was consuming too much of CPU. The algorithm is modified in CR6 to have all the costly operation done at MMS start time and just use comparison's and other simple calculations at runtime.
