This class is implemented based on the proto2 reflection. The performance should be good enough for normal usages. However, for places where the performance is extremely sensitive, there are several alternatives:
Note on handling of google.protobuf.Any: MessageDifferencer automatically unpacks Any::value into a Message and compares its individual fields. Messages encoded in a repeated Any cannot be compared using TreatAsMap.
Note on thread-safety: MessageDifferencer is not thread-safe. You need to guard it with a lock to use the same MessageDifferencer instance from multiple threads. Note that it's fine to call static comparison methods (like MessageDifferencer::Equals) concurrently, but it's not recommended for performance critical code as it leads to extra allocations.
