page finishes loading but progress bar continues very slowly

[Timo]

My (intranet) aspx page finishes loading but the progress bar continues to
advance very very very slowly, i.e. a new chunk on the bar is added 10
seconds or so, and then progress bar stops about halfway and never gets any
further. Is there any way to monitor activity on the web server that would
give some indication as to what process is still ongoing that makes the
browser (IE6) display the progress bar?

The page uses a hidden IFRAME to fetch data from a database, and contents
from the IFRAME are copied over into a DIV on the page, which is then made
visible. The database fetch and the copy from IFRAME to page-DIV occurs in
less than a second.

Thanks for any help or suggestions.
