I would like to know how long does it take ESP8266 to scan a list of APs and connect to the one with the strongest signal? By the way, how can the list of APs be expanded to around 20, if possible?

I don't have any concrete numbers, only what I have noticed when testing my ESP. In my case fetching the list takes something like 5 seconds, and connecting (to a known host, so without scanning) takes anywhere from 1 to 5 seconds. So all together I would assume somewhere between 5 and 10 sec to scan, pick the right one and connect to it.
What do you mean by expanding the list of APs to 20? I do not believe there is a limit to how many SSIDs that can be scanned... If you mean list of remembered APs then I believe that the latest SDK states that max is 8.
