Where can I find this patch? I'm on one of the ASUS routers but want to try out LEDE, but don't want reduced throughput.
I think these are it: https://forum.lede-project.org/t/qualcomm-fast-path-for-lede... https://github.com/gwlim/Fast-Path-LEDE-OpenWRT
GWLim's patch is the fastpath patch and a whole lot of micro-optimizations, so unless you're on a MIPS arch it's going to be hell to get working.
The cleaner patch, taken from QSDK upstream is here: https://github.com/lede-project/source/pull/1269

There's a patch to enable Qualcomm FastPath in LEDE, this offloads simpler TCP and UDP traffic from the Kernel stack and gets me 960Mbps LAN to WAN on a Netgear R7800.
Why isn't the patch upstreamed?
Because stuff is only upstreamed when it's totally stable and known to work on a wide range of devices, it's still a tad experimental (albeit many people are using it successfully)

Thanks for the tip; I'll have to check this out! My router's OpenWRT wiki page has had an ominous warning about reduced NAT throughput for some time. Turns out that my router should be supported (Atheros AR9344 MIPS 74Kc based).
Here's the pull request, I think you'll have more luck with this than gwlim's builds: https://github.com/lede-project/source/pull/1269

#245This issue has been fixed by a new firmware release from TP-Link. The updated firmware changes the behavior to use ICMP pings on the local network rather than NTP+DNS requests out on the public internet.
