I’m not connected to GL-iNet
Try this… this is just once thing, but it’s reproducible, and shows possible max performance.
openvpn --genkey --secret /tmp/secret
time openvpn --test-crypto --secret /tmp/secret --verb 0 --tun-mtu 20000 --cipher aes-256-cbc
Data - throughput is MB/Sec - time in seconds/3200

Pricing is actually fairly good for supported 3700 devices - see Netgate’s SG1100 device, same chipset, similar specs - $179USD
Yes, the EspressoBIN community board for 3720 is $93USD on Amazon with an enclosure and power supply, and a 32GB Samsung EVO microSD, no SW, no eMMC, and there, you’ll get no vendor support
Pricing here is driven by several factors - the cost of the chipset (3720 plus Topaz), and the NRE needed to develop the board - Netgate has a custom spin on the EspressoBIN, and Brume is a custom board.
Manufacturing Costs, aka MAV, are about the same - so cost of goods shipped is BOM+NRE+MAV/number of units shipped - and then add distribution costs to this.
$129 is a fair price, IMHO…
