max number of websockets about dart_frog HOT 3 CLOSED

This is an interesting question and I am also curious about the limits here. Some stuff to consider:

• System constraints go from OS configurations (ex: max open files) to hardware resources (ex: RAM memory)
• Don't use the dev server (dart_frog dev) as a performance metric.

I am curious what error you see when that apparent limit is reached.

I repeated the test with a dart app (not flutter) and it only opens the exact same number but now i have an error message "SocketException (SocketException: Connection failed (OS Error: Too many open files, errno = 24)", so it's an OS issue.

I managed to fix the error by editing /etc/security/limits.conf and running ulimit -n 1000000 (this time on a linux machine) and it went up to 20k websockets, but beyond this limit I understand that you need to set up more ip addresses.
