Servo cannot reach the desired control rate about moveit2

[AndyZe]

It looks like changing to the online_signal_smoothing::ButterworthFilterPlugin instead of online_signal_smoothing::AccelerationLimitedPlugin does help, it increases the control rate to ~75 Hz. But that's still lower than the requested 100Hz, which used to be easy to achieve. Previously 1,000 Hz was achievable.

I see a lower rate when I try to toggle directions back and forth, maybe because there is some dead time in between switching keys somewhere between me and what servo receives.

But if I just hold down a button and go right into joint limits/singularity, I hit 100 Hz no problem on my 4 year old laptop?

Here's another one in which I am just spamming arrow keys in twist mode.

You're right, it must be some kind of Linux button debouncing issue.
