Thank you for your response. To address your points:

- control-F5 makes the page still load in 0.5secs for me, same as refresh. it shows fresh data if added to the database file too, I'm am not viewing a cached copy to the best of my knowedge, and why would my machine cahce the results and non-one elses?

- if I replace the printing of the HTML output with the printing instead of the stopwatch results, the results display instantaneously on any machine.

This is all AFAIK - as I say, it works fine on mine so I am relying on what others tell me - I consistently here they experience a 30second delay for the HTML to generate on their screen. If you (or anyone else) wants to email me, I will provide the URL and/or code on an individual basis if you want to check it.

Thanks for the help so far - Dan
