Here are the results of Woodstox evet readers vs stream readers (running the same tests as above against XB)


|| *
* || *event readers*
 || *stream readers
* ||
| first run (in ms) | 101.6 | 85.8 |
| next 1000 runs (in ms) | 541.2 | 464.8 |

And here is the average of 10 AS 6 trunk start-ups comparing Woodstox event readers against SAX:
Woodstox: 18223.2 ms
SAX: 19038.3 ms

The results of the AS start-ups were very inconsistent. I.e. (I actually have booted the AS many more times) sometimes SAX would boot in 17 sec + something and Woodstox in 22 sec + something. But still on average the difference is probably close to the one above.
When I was testing the start-up I was offline, no anti-virus or other heavy processes. It's on windows vista.
