Dear Rick,
I still use WC 6.06 with great satisfaction.
As you know, every web page is encoded in a small script file of a few KB.
However, when the page is executed fields are filled with data, grids are loaded with rows, images are also loaded and therefore the "weight" of the page changes.

Is it possible to know how many KB or MB a web page weighs during runtime?
Many thanks for support

Yes - use the Browser Developer Tools (F12 or Ctrl-Shift-I).

• In the browser press F12
• Open the network tab
• Refresh your page (use Ctrl-F5 for a full reload)

optionally check disable cache in the toolbar to 100% ensure you're not getting cached content

The bottom of the panel should show your loaded byte size. The two values are actual loaded bytes (the first smaller value), and the full payload requested including cached content.

If you're not using these tools you should really spend some time getting familiar with them - they are immensely useful for debugging and optimizing Web apps.
