Unifi Express - Poor VPN Client Throughput

Received my Unifi Express yesterday in the UK (kudos on the fast delivery). Not sure if I am expecting too much but the VPN client performance seems very poor. I am seeing no more than 4Mbps down/up. Any other early Expess adopters seeing similar throughput levels?

I’m definitely interested in hearing the results from others too as that would be… concerning. Your initial results push me toward a UDR (if it ever goes back in stock), though I’m hoping for something in a small-ish form factor with a bit more power.

I just posted in another thread but also here: Got my Unifi Express lately and configured several WireGuard VPN clients, including Proton VPN, and speeds average at around 20-30mbit/s. To compare: When using the native VPN clients for, in my case iOS and macOS, I’m seeing 500mbit/s (my connection is a 500mbit/s fiber). CPU seems to be not under huge strain, but maybe it’s more like MTU or a different settings-based error. However, this is not something I can configure in the Network app in Unifi. Let’s share here if any solution can be found.

I submitted a ticket to unifi, sent all my logs and Screenshots. Their reply : “I have verified the speed with my internal team, and the throughput you are experiencing aligns with the expected performance from UNiFi Express.”
I am a bit disappointed to be honest.

Thought I’d follow up on this to say I’ve changed from OpenVPN to Wireguard and now seeing 15Mbps down.

Further context: Test was run against a ProtonVPN UK server. Tried multiple nodes and saw same results unfortunately.

Sorry - only just seen this. I’ve ended up ditching the Express and buying a UDR. I have found the Express to be quite buggy and needs a reboot every 5-7 days. Eventually the GUI grinds to a halt and connectivity is inconsistent both on the WAN and LAN side. Hopefully software updates can fix this over time but it was causing frustrations.

Hi Steve, I observe the same. I use Mullvad VPN via WireGuard I reach no more than 20 MBits. OpenVPN performs worse. I think it’s because of the CPU.

And you are in the UK, judging from your name?

Interesting, what are your max. speeds (download and upload) with a VPN on the UDR?

Glad it’s not just me! I’d hoped for better performance despite the lower price point.

Yeah located in the UK. Tested on both Proton and Nord UK servers and both gave same results unfortunately.

70mb but that’s my ISP limit. A friend of mine gets 220mb using Wireguard to ProtonVPN on his UDR (500mb connection).

Where were you able to grab a UDR from UK? Been struggling to find one

I bought a brand new sealed UK unit from a store on eBay only because I was offered an eBay voucher.
