Troubleshooting • Re: Slow VPN speeds

So I tried to set up iperf3 server on the Raspberry Pie. I then ran a test using my laptop on the local LAN. This was the result:

Code:

iperf3 -c 192.168.1.50 -p 11111Connecting to host 192.168.1.50, port 11111[  4] local 192.168.1.78 port 54613 connected to 192.168.1.50 port 11111[ ID] Interval           Transfer     Bandwidth[  4]   0.00-1.01   sec  1.88 MBytes  15.6 Mbits/sec[  4]   1.01-2.00   sec  2.38 MBytes  20.1 Mbits/sec[  4]   2.00-3.00   sec  3.50 MBytes  29.3 Mbits/sec[  4]   3.00-4.00   sec  3.62 MBytes  30.4 Mbits/sec[  4]   4.00-5.01   sec  3.62 MBytes  30.2 Mbits/sec[  4]   5.01-6.00   sec  1.25 MBytes  10.5 Mbits/sec[  4]   6.00-7.00   sec  9.88 MBytes  82.8 Mbits/sec[  4]   7.00-8.01   sec  10.1 MBytes  84.6 Mbits/sec[  4]   8.01-9.00   sec  10.2 MBytes  86.5 Mbits/sec[  4]   9.00-10.00  sec  9.12 MBytes  76.4 Mbits/sec- - - - - - - - - - - - - - - - - - - - - - - - -[ ID] Interval           Transfer     Bandwidth[  4]   0.00-10.00  sec  55.6 MBytes  46.6 Mbits/sec                  sender[  4]   0.00-10.00  sec  55.6 MBytes  46.6 Mbits/sec                  receiveriperf Done.
Then I connected to my wife's cell phone using the mobile hotspot on her phone from my PC and activated Wireguard, ran the test again, This was the result:

Code:

iperf3 -c 192.168.1.50 -p 11111Connecting to host 192.168.1.50, port 11111[  4] local xx.xx.xx.xx port 29938 connected to 192.168.1.50 port 11111[ ID] Interval           Transfer     Bandwidth[  4]   0.00-1.01   sec   512 KBytes  4.17 Mbits/sec[  4]   1.01-2.01   sec   384 KBytes  3.13 Mbits/sec[  4]   2.01-3.00   sec   512 KBytes  4.23 Mbits/sec[  4]   3.00-4.01   sec   640 KBytes  5.18 Mbits/sec[  4]   4.01-5.01   sec   640 KBytes  5.28 Mbits/sec[  4]   5.01-6.01   sec   640 KBytes  5.24 Mbits/sec[  4]   6.01-7.01   sec   512 KBytes  4.19 Mbits/sec[  4]   7.01-8.01   sec   640 KBytes  5.23 Mbits/sec[  4]   8.01-9.01   sec   768 KBytes  6.32 Mbits/sec[  4]   9.01-10.01  sec   640 KBytes  5.23 Mbits/sec- - - - - - - - - - - - - - - - - - - - - - - - -[ ID] Interval           Transfer     Bandwidth[  4]   0.00-10.01  sec  5.75 MBytes  4.82 Mbits/sec                  sender[  4]   0.00-10.01  sec  5.74 MBytes  4.82 Mbits/sec                  receiveriperf Done.
For fun I tried to run iperf3 from a wired PC. This was the result:

Code:

iperf3 -c 192.168.1.50 -p 11111Connecting to host 192.168.1.50, port 11111[  4] local 192.168.1.30 port 10267 connected to 192.168.1.50 port 11111[ ID] Interval           Transfer     Bandwidth[  4]   0.00-1.00   sec   112 MBytes   944 Mbits/sec[  4]   1.00-2.00   sec   112 MBytes   942 Mbits/sec[  4]   2.00-3.00   sec   112 MBytes   940 Mbits/sec[  4]   3.00-4.00   sec   112 MBytes   940 Mbits/sec[  4]   4.00-5.00   sec   112 MBytes   940 Mbits/sec[  4]   5.00-6.00   sec   112 MBytes   940 Mbits/sec[  4]   6.00-7.00   sec   112 MBytes   940 Mbits/sec[  4]   7.00-8.00   sec   112 MBytes   940 Mbits/sec[  4]   8.00-9.00   sec   112 MBytes   942 Mbits/sec[  4]   9.00-10.00  sec   112 MBytes   942 Mbits/sec- - - - - - - - - - - - - - - - - - - - - - - - -[ ID] Interval           Transfer     Bandwidth[  4]   0.00-10.00  sec  1.10 GBytes   941 Mbits/sec                  sender[  4]   0.00-10.00  sec  1.10 GBytes   941 Mbits/sec                  receiver
So now I'm even more confused... My internal wifi seems pretty slow to begin with. (using Unifi UAP 7). And as you can see the VPN test is incredibly slow
