Still trying to get to the bottom of the server issues.
You will see from my earlier note I have turned Federation back on.
But images are down while we work on stuff.
Sorry this is trial and error, but we will get there.
I expect t update this post with the latest later this evening.
Stay tuned.
Good news, these tweaks have fixed the cpu spikes and the Disk i/o spikes.
You should be seeing better performance.
Still researching what is causing the images not to display.
