Hi John,
Try refactoring so that the PipeParser is reused between calls. The first
time a PipeParser encounters a given message type, it spends a bunch of
time (although certainly not 2.5 seconds on any of our systems here)
building up an internal in-memory representation of the message structure
so that it can efficiently parse future messages of that type.
Cheers,
James
