Performance issue on Rpi5 and Hailo8

hi ,
i am having a slow performance when running networks on hailo8 , even models from the hailo model zoo and hefs.
with hailortcli run “hef” , i am having almost half the FPS and TOPS of the performance benchmark

hi,
can you check if you are running pcie gen 2 ?
you can do that by running the following command in rpi5
sudo lspci -vv
look for the speed of the pcie ( Hailo8) if it is up to 5GT/sec per lane , if its lower then its gen 2 and you have to upgrade to Gen 3.
