New Mac user, slow speeds, what should I expect?

[Subwoofer 0]

Hi there,
I'm brand new to the VPN world. I just upgraded my home service to 1GB fiber and want to use AirVPN for torrenting.
First thing I'm doing is trying out Eddie and checking speeds with speedtest.org
My speeds without VPN on my Wifi MacBookPro are 600mbps up and down. Latency is 10ms.
My speeds with AirVPN are anywhere between 40 and 200mbps max, depending on the server and protocol. I've tried a handful of servers and also Wireguard protocol.
I've tried 2 different Macs, an Intel macBook Pro and Mac Mini M1, both Wifi and wired connections. Speeds are the same for both.

I'm wondering what speeds should I expect using Eddie + Wireguard protocol?
Is speedtest.org the best way to check speeds while using VPN?

thanks!
