So i have ATT Fiber.
ONT Box>>>BGW210-700(IP PASSTHROUGH)>>>R700P

I have already checked my cables. The R7000P got a new cable when i added it in. Before flashing to DD-WRT, i can get my standard 800-900Mbps

Once flashed on DD-WRT...down to 300-400

I have seen that Shortcut Forwarding Engine enabled helps but it was on be default(i have a drop down for Disabled, SFE, CTF)

Firmware: DD-WRT v3.0-r47528 std (10/10/21)

Have no idea what build you flashed, but CTF would be a better idea. I can't remember if FA works on this router or not as I have only enabled CTF on mine and the logs for it are not handy.

R7000 has 1hz dual core Broadcom CPU and 300-400MBit is the max it could do practically, this is its max WAN speed...probably it could do a bit more with SFE but not guarantees...bear in mind SFE could interfere with some services too..
For 1 igg WAN speed you'd need more powerful router...
like R9000 or PC x86 /64 DDWRT box... close to gig R7800 could do as well..
Many discussions on the subject...check the forum

I have to agree w/ @Alozaros here. I have the ASUS RT-AC68U, which is very similar in specs, and of the same era. And ~300Mbps is all you're going to get w/o CTF/SFE/FA support. And while these will significantly improve performance, I consider them "hacks" and illegitimate since they break things. I think it's bad form for these so-called "features" to be enabled by default for this very reason. FYI; you can disable your firewall and connection tracking too and improve performance!

[egc]

Although I agree with @eibgrad, using CTF+FA will get you above 800 Mb/s WAN<>LAN throughput, but it has a tendency to break things like port forwarding and connection tracking (depending on your setup).

My main routers which do the work are NetGear R7800 which has near gig throughput without any "hacks"

[kernel-panic69]

I can verify that the R7000P will get more than 400Mbit/s throughput. Since the (re)introduction of CTF and the addition of FA, though, SFE does not perform like it used to on Broadcom (but it was for Atheros to begin with, anyway).

[Antimatter]

I have a R7000 running r45592 and it does 750Mbs down and up. Qos is off and SFE is on by default. This version of DD-WRT does not seem to have CTF or FA or I do not know where it is located as there is no dropdown on the main setup page.
I did an upgrade awhile ago to r47305 and my speeds dropped to 450Mbs down and up. I did not change any setting in r47305 and just reverted back to r45592 where the speeds again went to 750Mbs.
I seems the the R7000 is capable of over 450Mbs with certain versions and or the correct setting of DD-WRT.
I intend to try one of the latest versions and change the SFE/CTF/FA settings to see if the newer firmware will get back to the 750MBs speed that the older version attains.

[kernel-panic69]

And the R7000 is *not* the R7000P. CPU and wifi chipsets are not identical.

[Antimatter]

That is true it is not an apples to apples comparison but my real point is that on the R7000 the older firmware has higher speeds than the newer firmware without any changes so it would be something for the OP to try to see if the R7000P behaves the same.
And to be clear I do not know that if some settings were adjusted in the newer firmware that it may perform just as well as the older version.

[kernel-panic69]

And that right there sums up why unmaintained information causes issues. There's likely defaults that have changed since 44xxx and 45xxx and 46xxx builds, not to mention the few and far between Broadcom driver "updates", kernel patches, etc., among other things. And there was information that was posted that didn't quite apply to AP modes, which resulted in a whirlwind of user-inflicted issues.

[Per Yngve Berg]

Clearly the expectations are to high here.

CTF is the fastest as it work on the switch, dispatching the packets WAN-LAN without sending them through the CPU. This is a Broadcom specific feature.

SFE is a software acceleration. The packet goes through the CPU, but skip some firewall rules.

Now to the hardware:

There is a 1 Gig connection between switch and CPU that is shared between LAN and WAN. You cannot get a 1 Gig throughput, as packets have to pass here twice (LAN-CPU-WAN).

The CPU itself may also get overloaded by encrypting wifi, VPN etc.

[kiran]

Just my two cents but Netgear's website says the R7000 supports up to 1.9Gbps.

Comcast upped my speeds from 400 (which I was getting) to 800, and then 900 shortly after, yet I never got more than about 425mbits. I finally decided to connect directly to their modem (after taking back out of bridge mode) and to my surprise I get 940mbits.

I then decided to put the stock firmware back on the R7000, and sure enough, I get 940mbits. Now I don't know if it's using CTF or SFE or WTF but it does work at the higher speeds.

[egc]

The stock firmware also uses CTF+FA so you have to enable that.
With that enabled you should get 800+ Mb/s.

Why you are not getting the same as stock is because stock uses an obsolete Kernel 2.6 and although obsolete and probably not very secure any more, it has one advantage, because it is missing so many things it is faster.

Steve Jenkins did a nice comparison comparing speed on kernel 2.6 and kernel 3.X (I am sure @kp69 has that link somewhere )
