I just hit a situation which pushed me to ask this question:
I have about 150 active monthly users and I just hit 1k concurrent connections on a single day.
I did research and found many questions on “firebase concurrent connections” topic and those who refers to user-to-concurrent ratio say that on average it’s close to 1 concurrent = ~1400 monthly users (like here and here).
I’m now trying to understand if I really did something wrong and if yes, how to fix that?
The questions are:
- Is it look ok to get 1k concurrent connections with about 150 active users? Or am I reading it wrong?
- Is it possible to profile concurrent connections somehow?
- What are the typical “connection leaks” when it comes to chrome extensions and how to avoid them?
So far the architecture of the extension is that all the communication with firebase database is made from the background persistent script which is global to a browser instance.
And as a note, 150 active users is an estimation. For upper boundary I can say that I have 472 user records in total and half of them installed the extension and uninstalled it shortly after that – so they are not using it. And about 20% of the installed instances are also disabled in chrome.
