So the win would mostly be in smaller responses; the fact that we don't need parsing would just be a result of that. > My results show that the fraction of > query execution time that is required for the local processing is negligible.

Good, then the only remaining argument is quite weak. I'm fully convinced now; I will update the client implementation to reflect this. Thanks a lot! Ruben
