If Gather is running slowly and you've already tried these troubleshooting tips, it's helpful for our team to have a performance profile to assess the root cause of the issue.
How To Create a Performance Profile
Open Developer Tools in your browser (Shift + Ctrl + J) or in the Gather Desktop App (Ctrl+Alt+I).
Go to the Performance Tab and click the little circle button to start a recording.
Move around your Gather space to show us the issue you're running into. Once you've captured it, return to this tab and press Stop to end the recording.
