Orion startup is really laggy. This is not new to this version. I noticed it for months.
I have 2 tab groups with 10 and 12 pinned tabs. They are all suspended on startup and switch in-place is enabled. So other than their icons and 1 active tab, nothing else should be loading. However, the browser is hanging with the spinning wheel as shown in the video. Seems Orion is processing lot of stuff on startup.
The "lag" usually last about a minute then will be back to normal.
There should be no lag on startup, especially with only 1 active tab while other tabs are suspended.
