LiveShare Slow after a few hours use

Type: Performance Issue

After using liveshare for a while, IO operations appear to lag heavily. Searching files, saving files, and attempting to jump to functions and other areas of code, as well as F2 replace of variable/function names is near impossible with each action taking minutes. The project is a Javascript React project, incase this helps narrow down something specific though I have experienced this with all kinds of JS and TS projects with both M1 Macbook Pro, and 2016 Macbook Pro models as hosts.

This computer is the connection to live share, with the Host being an M1 Macbook Pro - performing any of these actions on the Host computer works flawlessly which leads me to believing it's liveshare's problem.

After disconnecting from the live session, restarting VSCode, and reconnecting to the same live session the problem is resolved for another hour or two after which it reoccurs. I don't think this is a memory leak or related to memory as I have plenty free (over 40GB free) as the included sysinfo should show. CPU usage is also under or around 25% for the Code instance and this doesn't rise.

I'm at a bit of a loss on anything I can do to diagnose further though as it's not easily reproducable in a quick amount of time - only after an hour or two of use.

Once this issue occurs again, I will use the electron devtools to record a performance profile.
