My advice may sound weird, but it might work for you (I took this approach once, and it did reduce the 1-item processing time from 15s to 3s 😄 - identical thing - get a list of items, go to the page, grab 30tish parameters).
And the advice is... turn off JS on the page.
Instead of opening the page, open the page source in the tab, use UI automation to send ctr-a + ctr+c, grab source code from the clipboard, and parse it with regex to get the values you need 🙂
You need to use UI automation to get the text because as soon as you disable JS on that page, you are disabling the PAD extension on the page (just that page, if you disabled JS for a single page).
This approach will work if values you are interested in are present in the source, and you can identify patterns and write regex or them. Speed boost guaranteed 😄
