Too fast--Strange

[CIAOBUBU 0]

Hi Everybody,

I have a question, which maybe seems strange to you..
I'm usign airvpn on a raspberry pi4.
The last time i have made a speedtest(3-4 monthes ago) it was "as usual" 60Mb/s symmetrics.
Yesterday i have reinstalled the os (ubuntu server 20.10) and i've coppied the folder containing the hummingbirdsexecutables. Today I've done a speedtest, justo to make a check:
 
It's runnig more than 3x....

I'm using:

 ./hummingbird --version
Hummingbird - AirVPN OpenVPN 3 Client 1.1.1 - 7 January 2020

You need to be root in order to run this program.

ubuntu@ubuntu:~/eddie$

runned whith:

/hummingbird --network-lock on --cipher CHACHA20-POLY1305 /home/ubuntu/eddie/profile1.ovpn

whith file profile1.ovpn containing:

client
remote 213.152.186.162 443
resolv-retry infinite
nobind
persist-key
persist-tun
auth-nocache
route-delay 5
verb 3
explicit-exit-notify 5
push-peer-info
setenv UV_IPV6 yes
remote-cert-tls server
comp-lzo no
data-ciphers CHACHA20-POLY1305:AES-256-GCM:AES-256-CBC:AES-192-GCM:AES-192-CBC:AES-128-GCM:AES-128-CBC
data-ciphers-fallback AES-256-CBC
proto udp
key-direction 1

 any idea on why it's so fast now or why it was so slow before?

Thanks all!
