At best it will add whatever the extra hop is and any network congestion. My VPS host is 2200km away. I should find a closer one… but it adds 160ms with some spikes in the 200-300 range. This is round trip 4400km roughly All things considered not too bad. My VPS is a 1vCPU, 1GB ram, 1Gbit unmetered, only as wireguard server. Hope that helps.
