Raspberry Pi 4 and bad latency.. SOLUTIONS?

on ny m73 i have a jitter of 1000... so what is the reason thst you say that this latency is good???? thanks

Assuming you use the 7c81's FGPA for stepgen and don't sofware step, you don't need a base thread so latency requirements is much relaxed. I'd be happy with anything under 130,000 with 200,000 at a pinch

or a 7i92... i payed for both cards 100 euros...

so for my information... on a normal pc like optiplex 3020m or lenovo m73 tiny.. i have latency under 2000... but i never looked this way in the histogram.

can you explain me the spike?! please

same values or i am wrong??

Note the missing spikes (colored in blue/red) at the extreme left and right of the graph.

and what does this mean? thanks

Latency excursions beyond the visible graph area.
