Hi xenomai, We have a new machine. When we installed Debian 11 (kernel version 5.10.199, Xenomai version 3.2.4), the latency test results were quite good — the maximum latency didn't exceed 40 µs. However, after upgrading to Debian 12 (kernel version 6.1.121-cip34, Xenomai version 3.2.6), the latency got worse, with the maximum exceeding 100 µs. What caused this change? The new kernel was built using the old kernel configuration. Is it possible to optimize the latency in Debian 12 by tweaking the new kernel configuration? New machine: Giga Computing MW53-HPU0；CPU：Intel Xeno w3-2425 Thanks for any suggestions. I've attached my configuration.
