问题
I am looking for latest, memory efficient and high-performance java XML parsing API. I need to parse 3 MB to 5 MB XML files.
I did google on this and come to know about Sun Java Streaming XML Parser (SJSXP) and Woodstox is much faster than DOM & SAX. Both are using StAX API. *schema validation is not supported by these technologies.
Aalto XML processor is also implements StAX API.
I have not found concrete findings on performance on these technologies.
Which one will be best in context of memory efficient, high-performance and ease of use ?

As to performance: SJSXP is the slowest; it's just a repackage internals of Xerces, wrapped in Stax API. This has some negative effects on performance (since it's not really designed for pull parsing). Woodstox is bit faster; much faster for small documents and writing, less difference when parsing longer documents.
And Aalto is by far fastest of the three, especially for parsing. It is commonly 50% - 100% faster than either Woodstox or SJSXP. One downside is that it does not handle DTDs (and thereby not external entities; it handles pre-defined and character entities).
