Gigabit WAN + SG-4860 - slow throughput

  • I have the 4860 and recently-installed Gigabit cable from Spectrum. Connected directly to the modem, I can get 940 mbps down/41 mbps up. Connected through the 4860, I'm lucky to get over 500 down (still can get 41 up). Running pfblocker on inbound-WAN outbound-LAN & Guest interfaces, DNSBL. Snort runs on LAN. System Activity doesn't show the 4 processors Idle drop below 80%.

    PowerD is set to Hiadaptive.

    I'm pretty sure the 4860 is supposed to support gigabit. Any help is appreciated!

    Thanks for any help!

    How does your WAN connect? DHCP? PPPoE? Something else?

    First, check Status > Interfaces and check for interface errors and see what the link speed/duplex is set to. I doubt you'll have a duplex issue at the speeds you are getting but it's worth a look.

    Next, disable snort, pfBlocker, etc and try it with just pfSense alone and see what you get. Adding more variables is not going to do anything but confuse the issue.

  • @jimp Thanks. I'm connected to WAN via DHCP (cable).

    I did try terminating the pfBlocker & Snort processes from the dashboard, and it had no impact in throughput. Do you think that was sufficient? I can of course completely disable them and see if that makes a difference.

    If it seems like a processor issue, I'll get the 5100, but seems like it might not do the trick since the CPU doesn't appear to be maxing out.

  • I'm able to get 950+mb on symmetric 1g fiber running pfblocker on a 4860. I would keep at the tinkering before pulling the trigger on a 5100.
