KRPC Joystick Input RPC/sec

[tomcunn]

I am trying to build an interface to a control panel that uses joysticks to interface to KSP via the KRPC. I have everything working, reading the joystick values into a raspberry pi, and then having the pi connect to the KRPC server. I am trying to achieve a 10Hz or better rate for the controls. For my python code, I execute the calls on a loop.

    while(True):
       GetJoyStick()
       start = time.time()
       vessel.control.pitch = joystick_pitch
       vessel.control.yaw   = joystick_yaw
       vessel.control.roll  = joystick_roll
       vessel.control.thottle  y= 1
       vessel.control.forward = 0
       vessel.control.right = 0
       vessel.control.up = 0
       end = time.time()
       print(end-start)
 

I played around with some different settings in KRPC advanced settings in the KRPC interface, the best I could get was 45 RPC/sec. Here is a print statement of time for the update to occur as shown in the code above.

I am wondering if this is the best approach that I am taking. For a bank of switches, the rates are fine, but for joystick control, it can be a little laggy.  Any help is appreciated. 

Thanks,
