We have implemented an optimization that cut down the number of executed database queries by SEF Advance. A somewhat higher number of database queries was being executed due to a change in handling aliases added in v5.3. We now moved back to the old way of handling aliases which will reduce the number of queries again. If you run SEF Advance 5.3 or 5.4 get the latest SEF Advance revision (v5.4.5) for optimal performance.
SEF extension for Community Builder has been updated for CB version 1.1 now. The activation link issue and session expired bug that used to occur with CB 1.1 in combination with the old extension should be gone now.
