I recently switched to fiber broadband with gigabit up and down, and I thought I would share (also for my own record) my experience with my pfsense setup.

Before switching, I had cable broadband with 250/10 speed. After switching to fiber, I noticed my original setup was limiting the throughput.

Maximum bandwidth (plugged directly into modem): ~940/940

Setup #1 (original):
Hardware: Jetway NC9C-550, N550, Realtek NICs, 2MB RAM, SSD, pfsense 2.2.6
Throughput: ~350/350 (behind switches)

Setup #2:
Hardware: Intel D2500CC, D2500, Intel NICs, 4MB RAM, SSD, pfsense 2.4.2
Throughput: ~500/940 (connected directly to pfsense)

Setup #3:
Hardware: Jetway HBJC311U93W-2930-B, N2930, Intel NICs, 4MB RAM, SSD, pfsense 2.4.2
Throughput: ~850/940 (directly to pfsense), ~775/940 (behind switches)

Setup #4:
Hardware: Intel DQ77, i3-3225, Intel NICs, 16MB RAM, SSD, pfsense 2.4.2
Throughput: ~940/940 (directly to pfsense)

I settled on #3 because of it's small and fanless. There might be room to optimize, but it's (more than) enough for my needs.

This is just FYI. If you have gigabit broadband, it would be great if you can share your experience.

Cheers!

I found the netbook boxes not very reliable for the GFiber 1Gbps speed, IMHO. I ended up building a PC around the AMD FM2+ platform with the A10-8750K

I am so glad to find this post!  I am a newbie to pfSense.  I have Gig fiber to my home.  I can get approx 940/920 Mb at my demark.  I have tried pfSense on three different machines connected directly to the demark and measured at a switch on the LAN side.  I see numbers varying in the mid 300s to just under 400 Mb each direction.  The CPU usage on each machine remains under 2 or 3% so it does not appear to be CPU related.  I am just starting to look at NIC hardware as a possible issue.  It just floors me how much throughput is lost through the firewall.  I would love to hear your thoughts on this.

Machine 1 is a Gigabyte EX58 MB (dial NICs) with:
Intel(R) Xeon(R) CPU W3680 @ 3.33GHz
12 CPUs: 1 package(s) x 6 core(s) x 2 hardware threads
AES-NI CPU Crypto: Yes (active)

Machine 2 is a HP DL380 G5 (don't have this one up right now to copy CPU info)

Machine 3 is a HP DL380 G7 with:
Intel(R) Xeon(R) CPU X5675 @ 3.07GHz
24 CPUs: 2 package(s) x 6 core(s) x 2 hardware threads
AES-NI CPU Crypto: Yes (active)

I didn't do a clean install on the G7.  I moved the drive (SSD) from the G5 to the G7 for a quick comparison.  I'll try a clean install on the G7 in the next few days to be certain of correct NIC drivers.

That sounds like you are not doing something your specific ISP requires such as putting your traffic on a specific VLAN or setting a VLAN priority. Or you're just connecting things wrong.

Those Xeons should easily be able to saturate gigabit.

What is the NIC hardware? 9Are they igb, re, rl, or ??)
