I will compare the Aruba AP22 with the much more expensive Engenius ECW230 costing around five times as much! I had another WiFi 6 router in the results, the Synology RT6600ax, but couldn't include it since it is still under NDA.
Real-life Tests
As expected, the AP22 remains behind the more expensive Engenius router, which has 4x4 MU-MIMO and a theoretical maximum combined speed of 3548 Mbps. The AP22 has 2x2 MU-MIMO and 1747 Mbps maximum transfer speed.
DiskSPD - OLAP
In an OLAP scenario, the difference with one client is notable, which is not the case with two clients.
DiskSPD - OLTP
Here is where things get weird. The AP22 achieves more IOPS with a single client, but loses with two clients.
LibreSpeed
In LibreSpeed, the AP22 is close to the Engenius in download speed, but notably slower in upload speed. That said, it achieves lower ping and jitter times.
LibreSpeed Mesh Network
I connected an AP12 to the AP22 to form a mesh network. The conditions were not ideal. The first one was installed into a steel rack inside my lab, which has solid steel walls. The second router was situated 8 meters away, outside of my home. I tried to install it inside the house but got no signal. As a client, I used a Lenovo Legion 5 Pro laptop, about 8 meters from the second router with two brick walls in between.
Speeds are not that high, but do note the distance between the routers and client, and the obstacles in between.
