[HAPI-devel] parser performance

[Tripp, B. <Bry...@uh...>]

I've done some work on HAPI parser performance lately.  The runtime had =
been
such that it might start to present a problem on a large EHR or MPI
application.  The changes are in CVS now.  With a typical ORU message, a
parse had been taking about 50ms on my laptop, but it has been reduced =
to
about 10ms.=20

There is also a new Parser (ca.uhn.hl7v2.parser.FastParser) for more
demanding situations.  You have to give it a lot of hints as to how to =
parse
each message type you are interested in, but once this is done, it =
parses
the same ORU in about 3ms.  Hopefully this will prevent some headaches =
as we
enter the EHR age. =20
