Labels: performance (was: )
> Don't allocate a Codec.Flag enum value array on every read

> In QueryOptions.Codec.Flag.deserialize() we call Flag.values(), which
> constructs a copy of the Enum array each time. Since we only use this lookup
> the enums, and since it happens _often_, this is pretty wasteful. It seems to
> make a few % difference to throughput.
