Sure, but you cannot really compare SGML::Parser::OpenSP to onsgmls as
the performance is relative to what you use it for. On my system,
processing the XHTML 1.0 SE Recommendation and ignoring all output
S::P::O should be about 30% faster than `onsgmls ...`. S::P::O's
performance drops significantly if you let it create Perl data
structures for all event data, if it does that for all events in the
beforementioned case `onsgmls ...` would be five times faster than
S::P::O minus whatever it takes to post-process onsgmls' output.
