I thought that this was an interesting CPU graph. On my lan i have a machine with 160 threads mirroring a ubuntu repository. I’ve pegged out the speed of my ethernet port on my cable modem or come quite close to it. ( I have some QoS rules enabled).
I also found out that my squid proxy had completely filled up the hard drive and I had to delete the cache, that was me and the yellow in the graph doing a ‘du -hs .’ but you can see the IRQ CPU USAGE taking it on the chin while handling the bandwidth.
