The only change I made was to include a url url that lists all the pages on my sites. After 16 hours the crawl had indexed less than 700 pages. Normal walk finishes with 11,000 pages in 18 hours. Could the size of my url file be the issue? there are 15,000 lines. I stopped the walk and all the walk data is gone. It shows the previous walk.
Not sure why it would be slow, but if you want to list all the pages instead of having the crawler discover them you should use page url instead of url url.
Yes, hitting "Stop" abandons the currently running walk. You can see the status for the abandoned walk from the Maintenance->Manage Logs->Profile Walk Status area. Use "Pause and live" to stop a walk and keep the data.
So this is just a help to find more pages. I would like the appliance to find these on it's own but it doesn't.
