AXParameter - Native SDK - Very high CPU Utilization

[rywager]

Has anyone else gotten to play with the AXParameter setup and noticed the extremely high CPU Utilization it creates?

When enabled, i see CPU% in "top" doubles from 25% to 50%. And the crazy thing is, the 25% my main binary is doing, is doing a LOT so for it to double just to listen to parameter changes is scary.

Should i add a sleep to the loop? Will that effect it's capabilities? Obviously waiting a second or more for paramters to update is fine i just wouldn't want the functionality to break and don't know that's the cause.

Am I doing something wrong or is this expected?

I believe this is just because i was using another loop on top of my main loop.
