That's with all the features on though right? I'm sure a lot of folks wouldn't be using VPN, deep packet inspection, ad blocking, a large number of routes and vlans, IDS, caching etc all at once, it hardly takes any CPU processing to simply route 2.5G (or hell, even 10G) through a firewall.
Solid points, but there’s a little bit of history (the details are fuzzy for me so apologies to anything I get wrong): When 1Gbps internet connections were starting to be widely available Unifi put out some “1Gbps” products that could only route 1Gbps with nothing turned on. It quickly dropped to 300Mbps if someone wanted to use any of the Unifi features and people called them out.
If they are making it a point to address that in this current product I feel like they want to make sure that type of call out doesn’t happen again.
This is surprisingly common, SonicWall devices are kind of market segmented by how much they can process with security services enabled. We installed 50/50 fiber at a customer location and their SonicWall had a gig WAN, but with the device set to "Maximum Security" it only got about 30-35 meg download speed. "Performance Optimized" let it hit the 50/50 lmao
