how to remove the 1sec delay of performTaskWithPathArgumentsTimeout

I'm using performTaskWithPathArgumentsTimeout in my ios ui script, and there seems to be a hidden 1 sec delay introduced before executing the command.

var target = UIATarget.localTarget();
var host = target.host();

var start = new Date().getTime();
var result = host.performTaskWithPathArgumentsTimeout("/bin/echo", ["Hello World"], 5);
var total = new Date().getTime() - start;

UIALogger.logDebug("duration: " + total);

outputs: duration: 1001

It the same for all commands. Instant when launched from command line, but they have this 1 sec delay when launched via performTask.

Any idea on how to reduce this delay ?

This has been cleverly solved by the instruments-without-delay project which changes Instruments to remove the 1 second delay in UIAHost.performTaskWithPathArgumentsTimeout

This delay is related to the way UI Automation launches the command internally. There isn't anything we can do from our end.

That said, if you have a lot of commands you are trying to execute in sequence, you can put them all in a shell script and execute it like so:

host.performTaskWithPathArgumentsTimeout("/bin/bash", ["some_shell_script.sh"], 5);

That will run the given shell script file within bash and you'll only have to pay the 1 second process startup penalty once.
