Slow Tailscale speed

I'm only getting an average of 9.21 Mbps from my Synology NAS to my remote Mac device. My NAS is connected to LAN with an internet speed of +-300Mbps. I don't expect 300Mbps through Tailscale, but a 80-100Mbps would suffice.

• Both are on 1.44.0
• It's a direct connection, no derp
• Average ping is 33ms

I'm clueless, anyone? Thanks
