Real-time performance tunning

Hi, I am new to Jetson AGX Orin and have just changed to the RT kernel: Linux ubuntu 5.15.136-rt-tegra.
To get good RT performance for motion, I have set nvpmodel to MAXN (60W) and isolate core 8-11. After these, the max jitter on isolated core of12h cyclictest test is still about 40us.
Wondering any other method to make RT performance better?

Hi,
Please run sudo jetson_clocks to fix the CPU cores at maximum clock. This should bring certain performance enhancement.
