This issue has occurred on mobile device (I'm on iPad mini 4, RAM 2GB, A8 Chipset, iPadOS 15.7.3)
To reproduce Orion being slow issue:
- Open a page which has lots of (about 30+) higher resolution (about HD - 4K) images, then scroll down the page to load all images.
- Close the tab.
- Do something such as a typing with keyboard (not physical keyboard).
On my device, typing with keyboard was slower after that.
There are another steps to reproduce this:
- Spam opening new tabs (approx 17+)
My device was being slow at this step.
- Close all tabs.
My device was still slow as step 1 after closing tabs.
