Posted: Sat Jan 20, 2018 7:22 Post subject: Gigabit throughput problem (WAN->LAN)
I recently bought a Netgear R7800 in hope to solve my throughput problem, but when I put the latest DD-WRT on there (01-19-2018-r34578) I still only get about half the speed I expect. With the original Netgear firmware I did see numbers of 900+Mbps, but now I only see about 500Mbps.
I upgraded (or so I thought) from a TRENDnet TEW-828DRU running DD-WRT v3.0-r27506 from 07/09/15 where I got speeds around 450Mbps. However, I guess it might have been DD-WRT limiting the speed there as well. Now I'm kind of lost and not sure how to get full throughput using DD-WRT.
What router can I buy to see full Gigabit speed if I want to use DD-WRT?
The R7800 on my ISP (Cox) will do about 860mbs without SFE enabled.
My R9000 will do 900mbs with or without SFE using Cox's internal speed test.
If I go to an external speed test it can vary from 500 and up.
Just because you may be allocated a 1gb pipe doesn't mean anyone can fill it for you.
I have a usenet provider that used to max out my previous 300mb service. When I switched to gb service I found out the usenet service was already maxxed out giving me 300mb. _________________ Segment 1 XR700 10Gb LAN, 1Gb WAN ISP BS

r7800 still cant do gigabit, but now with this broken kernel 4.x its far from it cause of a cpu load problem thats nearly doubling what it should be, even the wifi is capped to around 210mbps thats N300 speeds.. & the qos sucks too. BS's QA is out the window completely for years now.
want "proper" gigabit, like with qos on or off, no choice left but to assemble a desktop pc & install ddwrt x64 on it _________________ LATEST FIRMWARE(S)

Thanks for all input. I'm not really interested in using a dedicated PC as a router, but I do want best possible DD-WRT hardware router.
It's kind of surprising to me that there isn't a single DD-WRT router out there offering real Gigabit throughput. I might look into the Netgear R9000, or just use stock R7800.
If anyone have any other suggestion for which one to go with, please let me know.
btw. The first routers that popped up when I started looking for one with high throughput was Cisco RV320 and RV340, but as far as I can see they do not support DD-WRT.

I like the passive-agressiveness. Not sure if it's achieving anything, though.

Bullsh*t on the "no choice left". If OP is considering going x86/x86-64, there's lots of very good Router/Firewall distributions.
I think it'll be very hard to get full gigabit speeds with any consumer/SOHO router running DD-WRT or OpenWRT/LEDE. There's a probably a point where you need so much CPU power for routing that there's no benefit in using an embedded system, and you as well could use a x86/x86-64 system with a specialized OS, like for instance pfSense. You'd still need a WiFi router as an AP, but that's also the case with the Cisco hardware mentioned.
I am using Kong 34320 build with 3.18.91 kernel and just upgrade my Internet speed from 200mbs to 500mbs.
The computer connected directly to cable modem is reaching 500 mbs.
The r7800 is not able to achieve Internet speed more than 450 mbs with SFE on and QoS off. I guess SFE is not working right now or disabled.
Dear users, Whats ur experience? _________________ Netgear R7800

I've done some more testing and have very mixed feelings. When reading the responses yesterday I had already reverted to the latest Netgear firmware, i.e. I could not verify whether SFE was enabled or disabled during my testing.
Today, I decided to try the latest Kong build, "v3.0-r34320M kongat ( 01/02/18 )". I reverted to default settings during firmware flashing and before testing I confirmed that "Shortcut Forwarding Engine" was enabled (which it was by default).
While testing using Cox Speedtest (https://www.cox.com/internet/speedcheck.cox (requires COX-login, and they even limit the number of daily speedtests)), which tend to give me the highest result, I got numbers around 850Mbps. After applying tatsuya46's suggestions I got 932Mbps.
1. I'm not familiar with the difference between Kong-builds and the builds available at dd-wrt.com (Brainslayers?), but does Kong use optimized settings like SFE by default, and the other one does not?
I didn't see anything special when quickly browsing through the settings though (besides potentially the SFE).
2. @tatsuya46 What's the proper way to save that command?
Does the interrupt stay the same so I can just use "Save Startup" to have "echo 2 > /proc/irq/255/smp_affinity" run during boot-time, or do you have to get fancier than that?
3. After thinking I was happy with DD-WRT and the R7800-router I configured my static leases and my WiFi-settings etc to match my previous settings. The router totally locked up; even power-cycling didn't help at all. This scared me as my main reason for using DD-WRT is stability. Any comments on that?
Would I be better off to switch to Asus, or something else? Or has DD-WRT become unstable lately so it's better to stay away for those of us that only want a router to "set and forget"?
