Looking at a bare XML page in the pretty-printer. After downloading, the page
took 137 seconds to render and consumed 94Mb of [non-swapped] RAM. It was quite
a big XML page but not anywhere near big enough to justify this length of
rendering time.

The system is normally very responsive in both Mozilla and other programs, no
other major process was running at the time.

System Details:
Athlon 1200, 512Mb DDR RAM, 7200rpm hard disk.


Reproducible: Always

Steps to Reproduce:
1. Find stopwatch.
2. Start windows task manager.
3. Download URL.
4. Wait a while.

Actual Results:  
It took 137 seconds to render the page and consumed 94Mb of memory.

Expected Results:  
Lots faster and not so much memory.

This would fall under the "our XSLT engine is slow" category. Once we start
optimizing patterns we can probably save a lot of time here.
