Is the Timeout 40s in Swift dashboard max_execution_time?

Aug, 8 30
Not exactly. This shows how long can PHP script run. It is possible that max_execution_time is longer, but there is proxy timeout which stops the script earlier. It will be also 40s if the server doesn’t serve multiple threads for the same IP.

Is the timeout time of the server of 300s OK or is higher better?

Aug, 8 8
300 is the default timeout, however Swift will try to extend it up to 600s during autoconfig. If it is above or equal 40s it is ok, however higher timeout can speed up prebuild process.
