If you hammer the page and comment out the xpath will run for ever,
slow down sure but recover and memory never really climbs, with the
Xpath it will eventually run out of RAM you might need to run 2 or 3
times
ab -c20 -n1000 http://10.0.10.37:8888/test/index.cfm
If I stop it just before the memory runs low the page is then just
stuck on Yellow bluedragon errors with
BlueDragon Internal Server Error
The page you were executing caused an internal BlueDragon server error
