I recently switched to openwrt after dealing with the native firmware on my r7800 being frankly awful. The only downside to using openwrt is that I can only get around 480-500~ mbps when I could get a solid 900 with the native firmware. This is with the experimental hardware nat on, idk if it even works.
Is there a device that's going to eventually replace the r7800 as the most modern, well-supported device for openwrt (as far as I know)? There's the R9000 with its possibly much faster Annapurna Labs CPU or the many 802.11ax models that have come out. Is it known whether any of these will actually be fast enough for full gigabit software nat at all? I don't really see any standardized benchmarks of router CPUs so I guess it's unknown unless somebody tests it.
