Number one would probably be to ensure the rpi has a good cabled connection to the router (and make sure it uses it instead of WiFi). VPN connections going back and forth over WiFi would slow things down. Next bottleneck would probably be CPU. Check if the CPU is being maxed out or throttled when you’re using the VPN.
