OpenWRT 15/02/2025 snapshot for Pi5 No CPU Activity monitoring

[AndrewW-GIT]

Just installed the snapshot from 15/02/2025 on a pi 5 and works ok. I cant quite get maximum speed on a 1 GB network, but that is not the issue. The top command is showing 0% cpu utilisation for everything even when transferring 1gb a second and still capping slightly, so i cant tune the config. Am i missing a module or something or is this just a bug ?

Define "capping slightly".

losing about 70mbs, and looking to test irq balancing / off loading but i cant see the impact on the cpu. Hence my query about top not displaying utilisation. The part about capping was just back ground and the reason i need to see this data

My Pi 5 Snapshot from today is showing the CPU Activities in Luci

Thanks but that's not per process. Im trying to get the linux top command working so i can see per process

Are you saying that "capping" means that you're getting 930 Mbps instead of 1000 Mbps?

Are you receiving errors running the command - or are you just perplexed it reads 0%?

I might have found the answer, possibly. Packet Steering was not enabled. I have turned that on and will be running new tests. Current setting is 128 but ill test the 256 as well. I'm thinking because this is a Pi5 it's likely its not using the whole CPU due to this setting. Any thoughts?

It does appear that adjusting this setting is now offloading more to the CPU on the Pi5. I have yet to do a controlled throughput test yet to officially confirm.
