      Description

      Trying to implement MDL-50125 we found performance problems and we looked at possible solutions in MDL-50126.

      Caching plugins callbacks list at application level reduced the memory usage by around a 10% in user profile pages (not exact data, but 10% including MDL-50125 fix, so probably even more) although the new cache memory overhead, basically because the number of files included is reduced to half.
