* Revision 1.5 2001/05/11 13:26:27 tng
* Copyright update.
*
* Revision 1.4 2001/01/15 21:26:33 tng
* Performance Patches by David Bertoni.
*
* Details: (see xerces-c-dev mailing Jan 14)
* XMLRecognizer.cpp: the internal encoding string XMLUni::fgXMLChEncodingString
* was going through this function numerous times. As a result, the top hot-spot
* for the parse was _wcsicmp(). The real problem is that the Microsofts wide string
* functions are unbelievably slow. For things like encodings, it might be
* better to use a special comparison function that only considers a-z and
* A-Z as characters with case. This works since the character set for
* encodings is limit to printable ASCII characters.
*
* XMLScanner2.cpp: This also has some case-sensitive vs. insensitive compares.
* They are also much faster. The other tweak is to only make a copy of an attribute
* string if it needs to be split. And then, the strategy is to try to use a
* stack-based buffer, rather than a dynamically-allocated one.
*
* SAX2XMLReaderImpl.cpp: Again, more case-sensitive vs. insensitive comparisons.
*
* KVStringPair.cpp & hpp: By storing the size of the allocation, the storage can
* likely be re-used many times, cutting down on dynamic memory allocations.
*
* XMLString.hpp: a more efficient implementation of stringLen().
*
* DTDValidator.cpp: another case of using a stack-based buffer when possible
*
* These patches made a big difference in parse time in some of our test
* files, especially the ones are very attribute-heavy.
*
* Revision 1.3 2000/03/02 19:54:40 roddey
* This checkin includes many changes done while waiting for the
* 1.1.0 code to be finished. I can't list them all here, but a list is
* available elsewhere.
