[Help] High CPU Usage when downloading



  • Heey what's up PfSense forum, my first post hah  :P

    I'm having a question about high internet speed, currently when I do a speedtest I have roughly ~100Mbit speed
    When I'm looking in my PfSense the cpu will go higher then +70% and the admin panel 'n such will freeze up

    I've looked at the system activities and noticed this is eating all the CPU only when ~100Mbit is being used

    PID USERNAME PRI NICE  SIZE    RES STATE    TIME    WCPU COMMAND
      12  root              -56    -    0K    96K WAIT    0:31  67.77% [intr{swi5: fast taskq}]

    Even the OpenVPN will freeze up, so something is clearly wrong with this process
    Does anyone else have experience'd this and knows how to fix it ?

    I'm currently running:
    2.2.4-RELEASE (i386)
    built on Sat Jul 25 19:56:41 CDT 2015
    FreeBSD 10.1-RELEASE-p15



  • I'm having a question about high internet speed,

    How high the speed is there? The Internet connection I mean?  :(

    currently when I do a speedtest I have roughly ~100Mbit speed

    What kind of speed test? Through the Internet? Or from on to another PC by using iPerf?  ;)

    When I'm looking in my PfSense the cpu will go higher then +70%

    Which CPU, Cores, GHz, how many RAM, which architecture, which LAN Ports are in
    usage (Realtek, Broadcom or Intel)?  >:(

    and the admin panel 'n such will freeze up

    mSATA, USB Stick, HDD, SSD or SATA-DOM?  :o

    Even the OpenVPN will freeze up, so something is clearly wrong with this process

    Or is only the hardware not capable enough? Is this 32Bit or 64Bit Hardware you are using?
    Are their any free miniPCI or PCI slots in the system?

    Does anyone else have experience'd this and knows how to fix it ?

    Really fast hardware, with AES-NI or VPN (crypto) acceleration hardware support
    Multi Core (Dual or Quad) CPU ~@3GHz or around would be good, 4 GB or 8 GB RAM
    Intel NICs server grade or newer on board ones.  :-*
