| 84 | * Performance Patches by David Bertoni.
|
---|
| 85 | *
|
---|
| 86 | * Details: (see xerces-c-dev mailing Jan 14)
|
---|
| 87 | * XMLRecognizer.cpp: the internal encoding string XMLUni::fgXMLChEncodingString
|
---|
| 88 | * was going through this function numerous times. As a result, the top hot-spot
|
---|
| 89 | * for the parse was _wcsicmp(). The real problem is that the Microsofts wide string
|
---|
| 90 | * functions are unbelievably slow. For things like encodings, it might be
|
---|
| 91 | * better to use a special comparison function that only considers a-z and
|
---|
| 92 | * A-Z as characters with case. This works since the character set for
|
---|
| 93 | * encodings is limit to printable ASCII characters.
|
---|
| 94 | *
|
---|
| 95 | * XMLScanner2.cpp: This also has some case-sensitive vs. insensitive compares.
|
---|
| 96 | * They are also much faster. The other tweak is to only make a copy of an attribute
|
---|
| 97 | * string if it needs to be split. And then, the strategy is to try to use a
|
---|
| 98 | * stack-based buffer, rather than a dynamically-allocated one.
|
---|
| 99 | *
|
---|
| 100 | * SAX2XMLReaderImpl.cpp: Again, more case-sensitive vs. insensitive comparisons.
|
---|
| 101 | *
|
---|
| 102 | * KVStringPair.cpp & hpp: By storing the size of the allocation, the storage can
|
---|
| 103 | * likely be re-used many times, cutting down on dynamic memory allocations.
|
---|
| 104 | *
|
---|
| 105 | * XMLString.hpp: a more efficient implementation of stringLen().
|
---|
| 106 | *
|
---|
| 107 | * DTDValidator.cpp: another case of using a stack-based buffer when possible
|
---|
| 108 | *
|
---|
| 109 | * These patches made a big difference in parse time in some of our test
|
---|
| 110 | * files, especially the ones are very attribute-heavy.
