Request content is read one byte at a time

[m-mcgowan]

The read() method fetches request content one byte at a time. This introduces quite a significant overhead.

To make it more efficient, the data can be read as a chunk into a read buffer.

Did you fix this in your port for Particle? I think not or yes? Any implementation idea's (or examples that implement reading data as chunks?).
