So, I will not present you with a graph as it is a tedious process (probably it is some descending gaussian curve wrt timeout occurring).
But 100ms fails, 125 I had 1 port fail, at 140, 150 and 180 I saw timeouts resulting in fdb add fails, like (and occasional port fail):
mv88e6085 1002b000.ethernet-1:04: Timeout while waiting for switch mv88e6085 1002b000.ethernet-1:04: port 0 failed to add be:7c:96:06:9f:09 vid 1 to fdb: -110
At around 200 ms it looks like it is getting stable (like 5 runs, no problems).
So with the gaussian curve tail whipping ones behind (risque of failure) it might need to be like 300 ms in my case... :-)
