- * 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
