* _timeout_: For how long the recorder should be running in milliseconds. 5 minutes by default. Try not to set too high a value to this argument, since .trace files generated by `instruments` are pretty big in size.

+ * _pid_: The ID of the process to meassure the performance for. Set it to `current` in order to meassure only the performance of the process, which belongs to the currently active application (this might not work for some profiles).

Setting process ID while device under test is Simulator might require `instruments` to be launched with sudo privileges, which is not supported and will throw a timeout exception.
