Description

The struct 'read' method allocates a TField object on each readFieldBegin(). This adds up to a lot of garbage. The patch creates and reuses a mutable TField object for reading.

The patch modifies the TBinaryProtocol as an example, but the other protocols should probably be optimized as well (including TProtocolDecorator).
