The real-time performance of jetson xavier is very poor

Could you run sudo tegrastats and check if you can see the deviation?

Also, please share more details about the BSP release used, any steps followed before your test like etc, cyclictest command used with args and result.

Please run the test after setting the below values and share the results. Hoping it to help with latencies.
-# cat /sys/kernel/debug/tegra_mce/rt_window_us
-# cat /sys/kernel/debug/tegra_mce/rt_fwd_progress_us
-# echo 0x7f > /sys/kernel/debug/tegra_mce/rt_safe_mask
