Seems to be around 1 million. It's chunky and it's probably not well optimised for the build to be honest, but it was only starting to creep up the priority list as it crossed the 10m mark.
This is also the length on our CI which is running on some POS build machine. Locally it's far faster, but with Vite 8 its crazy fast.
I am still trying to work out what Teams is "setting up for me" when it takes several seconds from opening the bookmark in my browser to having a UI where I can read the chats. It's running on a PC that can render complex graphical scenes in real time but it takes half a minute to see "LGTM!". (Shaking head emoji goes here.)
Then again Teams is still barely an amateur compared to the incomprehensible slowness of Jira.
