Kernel? I presume you are talking about Machs kernel?
That was not using Mach that was a servo drive and motor sitting on the desk doing a move connected to the drives software and using the software scope in the drive software. Same Velocity, same acceleration, same everything with the exception of the interpolation of the encoder.

Hood,

Sorry about the reference to Kernal, I mean sampling rate

Not sure what you are meaning regards the sampling rate, if the scope then the sampling rate of it was exactly the same between tests. If the drive  then the Velocity regulator update rate is  250uS. and position regulator 1mS both fixed as far as I know.
The only setting changed in the drive was the interpolation of the sine/cosine encoder.
