Hello I am very new to everything so I don't know much
I have downloaded the rpi image from download page and installed it with Raspberry Pi Image app and I found my latency and histogram very bad.
I had installed linuxcnc a long while ago with the same stuff it was bookworm then so I was very worried and though I might just go back to that image but I notice something on histogram it said no_isolcpus. which I remember that I read that core 2,3 should be isolated so I googled how and isolated them and the latency became much better.
I took a screen shot of the histogram but it was saved in tmp /media/kunena/emoticons/
yeah I sadly left it at tmp then I needed to reset to isolate the cores so the screenshot is gone sadly. I only remembered after I started writing the post. sorry
