That depends on the CPU in that box, and the SSL library in use.
I am considering exchanging the remote router for a newer model (Asus RT-AC86U)
with more computing power...
AES-256-GCM is extremely fast on CPUs that have AES-NI support (usually
"Intel and AMD"). cipher chacha20-poly1305 is fast on some ARM families
that have hardware support for that cipher.
I don't know what CPU is built into these Asus routers....
Both routers are ARM based and you should not expect terrific
performance when using AES-GCM.
Asus RT-AC-68U:
This router incorporates Broadcom's new BCM4709 Wi-Fi chipset, the
cornerstone of which is a 1GHz, dual-core ARM Cortex A9 processor
(from
https://www.techradar.com/reviews/pc-mac/networking-and-wi-fi/modem-routers/asus-rt-ac68u-1262664/review)
Asus RT-AC-86U:
It is powered by Broadcom BCM4906 @ 1.8 GHz chipset, 512 MB RAM and
256 MB flash
(from https://routerchart.com/asus/asus-rt-ac86u-rt-ac86u-369 and it
seems to be 5 yrs old already; however the Asus website lists the
RT-AX-86U and it *also* uses a dual core 1.8 GHz CPU).
Expect output to be up to 1.8 times faster with the 86U.
