I get the slowdown thing going on in a different environment. Things just seem to freeze. Can carry on typing and eventually the machine catches up and displays what I type.
My development machine is a Windows XP laptop and it runs SQL Server, CF 8 and of course the IE web browser. Loads of RAM but the processor is a single CPU and 3 years old 1.4 GHz mobile processor. I recently got a new laptop, Windows Vista based, and found that when I access the application on the other laptop that I no longer get the slowdowns happening. Of course it is newer hardware, Core Duo & etc which would have some benefit. My diagnosis is of course, something related to the browser running on XP and maybe trying to do too many things at once on the single CPU PC. BTW the periodic slowdown happens on other apps on the same laptop (such as Outlook, Word etc). When I publish the app to the client environment, they do not see the slowdowns. Of course the production environment runs on a 'proper' server. So, if you are accessing your app running on a Linux server using an XP PC/Laptop then perhaps the cause might be the PC and not the server.
