So I recently upgraded to a Gigabit connection to my ISP and in preparation, I was reading on various sites about WAN-to-LAN throughput, and understanding how routers are achieving higher speeds via NAT acceleration, FAST NAT, QCA, SFE, whatever the vendors want to call it this day of the week.
At any rate, I was happy to see that SFE has been added as a feature recently to DD-WRT. I updated my router in advance of my install to make sure I had the option available.
So with SFE being available in DD-WRT now, I wanted to see if anyone out there also has a gigabit connection, and to see what kind of throughput you are seeing WAN-to-LAN both with and without SFE enabled, as well as without NAT/router (direct to PC).
So to start, I have the TP-Link Archer C9 AC1900 running DD-WRT v3.0-r32868 std (07/27/17). For those too lazy to look it up, it's a Dual-Core 1GHz Broadcom CPU setup.
Running DD-WRT on my router with SFE off, I am seeing speeds cap out around 450Mb down and 400Mb up.
Running DD-WRT on my router with SFE on, I am seeing speeds varying in the 700-825Mb range in both directions.
And just for reference, I can just about 'max out' my connection being directly wired to my PC without a router at around 933Mbit in both directions.
I have tried some various overclock settings (from 1Ghz all the way up to 1.6GHz), without really seeing any consistent improvement.
I'm thinking it might be worth it to look at some slightly better hardware if I want to squeeze every last drop out of my connection. I'm in no rush to do this, so I'm opening this thread for discussion to see if there's a router out there capable of running DD-WRT that can achieve 900Mb+ more consistently. I really like what DD-WRT has to offer from a functionality standpoint and would like to continue to use it in the future.
Hi,
Nice thread & it's really so nice that you have speed up networking service. I have taken WAN service from Wanos.co & they also working the same & also providing service every time.
Thank you

That discussion is quite closed by now. Before SFE you needed either WRT1900ACS or R7800 to get gigabit speeds. Now SFE is on the works so should improve in time. _________________ R6400v2 (boardID:30) - Kong 36480 running since 03/09/18 - (AP - DNSMasq - AdBlocking - QoS) R7800 - BS 31924 running since 05/26/17 - (AP - OpenVPN Client - DNSMasq - AdBlocking - QoS) R7000 - BS 30771 running since 12/16/16 - (AP - NAS - FTP - SMB - OpenVPN Server - Transmission - DDNS - DNSMasq - AdBlocking - QoS) R6250 - BS 29193 running since 03/20/16 - (AP - NAS - FTP - SMB - DNSMasq - AdBlocking)

My apologies if you feel that I'm digging up old discussions. After searching the forums some, I still don't have a clear answer to my question. I was hoping to hear what routers are capable of getting 900+ with SFE turned on. I looked at some previous posts with people looking at the R7800 and they were getting capped out around 550-600Mb (on DD-WRT, but full speeds on stock), so not really any better than what I'm seeing now.
I guess to simplify and rephrase, the question is:
What routers can hit 900Mb+ using DD-WRT firmware, with SFE on or just via raw power (with SFE off) ?
What build are you on now; still 32868? Try 33006 or 33215.
except R7000 or some router like that; you need to use native mac of router due to OEM custom rom inside cpu which limited speed of vlans port. that's all you can doable.

Been using 33006 lately, not much difference. I think there's an issue with 33215 or whatever latest is for my router.
Really contemplating building either DD-WRT x86 or pfsense box, but not finding reasonable low-powered hardware for the right price.

If you want to use all of your WAN speed then its not hard to do with an opensource FW application running on pc hardware.
pfSense is probably the most popular of the free FW distro's.
I run it on a 1st gen i7 pc I had sitting around in the basement.

You can easily find a lower end pc on ebay for $300-$400 which should provide more than enough HP to give you gig WAN.
Just make sure to have a 2nd NIC if it doesn't come built in. NICs are inexpensive.
Here is an example that would be in that price range.
search on ebay for this.

Lower power is a bigger deal for me. I have a guy I follow on ebay that sells SFF and USDT PC's for extremely cheap. In fact, I picked up (2) i5-3470s UDST PCs for about $150. Great HTPCs, but not quite setup right for what I want (no room for expansion cards really, and I don't think trying to do it over USB3 would be yield acceptable rates).
So it all depends on what I can find - maybe x86 router isn't for me if I'm trying to achieve energy efficiency.
Any clue what kind of latency would be added for a USB 3.0 network adapter, when trying to saturate the full 1Gb? I understand some of this could depend on the CPU as well due to the polling.

No, but a quick Google for "usb3 network adapter latency" seems to indicate it's pretty small or even negligible for USB3, assuming the adapter itself is good quality. I've used a USB2 100Mb/s adapter in the past, but never a USB3 GbE one. I would think for a firewall, you'd want the USB3 adapter for your WAN. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#
