... so I am still wonder if they have made any adjustments on PANOS to better support the PA220. I am still on 9.1.5 as I found 10 was awfully slooooow.
It's a bit of a pain in the rear-end that the gui takes a little more time to load (and the new "style" looks forced minimalistic), but other than that I don't think there's a real reason not to upgrade
(this didn't stop me from running it on my 220 however ;) )
Slow pa-220 web interface is still listed as a known issue in the release notes
