XML Parsing using XML Reader and Linq.

Description of Problem:

Streaming a 500k (64k gzip compressed) and parsing with XML Reader takes a very
long time.

Steps to reproduce the problem:
1. Run attached sample app.  Metrics are provided.
2. Wait ~40secs.

Actual Results:

Processing time for 500k (950 elements) takes ~35secs.

Expected Results:

Something much faster.  If the device can play 3d games, then parsing
1000records should be a walk in the park ;-)

How often does this happen?
