      Greetings,

      I have an Intel D2500CCE-based pfSense based box.  It has a dual-core 1.86 GHz processor, dual Intel 82574L gigabit adapters, and has served me well as my router through several bandwidth upgrades.  My ISP just increased our bandwidth to 1 gigabit, and I noticed that the box won't drive more than about 450 Mbit.  I've tested with iPerf directly to the box and I'm seeing high CPU related to interrupts.

      I've tried all the tuning suggestions at docs.pfsense.org and none make much difference.  I'm just looking for a sanity check–should this machine be able to drive gigabit at line rate?

      Thank you.

        unlikely to hit a gigabit, but you could try to see if pfSense 2.4 beta offers any improvement

          That sounds about right to me.

            If you are looking to upgrade to max your WAN, check out the J3355B.

            It's mini-ITX, SO-DIMM DDR3, will max gigabit, and is AES-NI so will continue to be supported by pfSense for many years.

            It's ~$57 shipped.

            You would need a PCIe NIC, an i340-t2 would fit your needs for cheap.

            $72.57 shipped.
