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

This may be a silly question, unless is isn't. Are you sure that your maximum upload speed is 300Mbps? Your maximum upload speed can be different to your maximum download speed. https://speedof.me can help you check.
If that's not the answer, sorry for possibly being overly simple, but some people might not realise.
300Mbps is definitely your upload and not download speed?
Yeah as others have said, unless you have a symmetric connection, 300 is download. Cable internet very often has good downstream and lame outbound. My parent’s comcast is something like 300/12 which would be in line with what you’re seeing. FIOS in my area is all symmetrical so gigabit is 1000mbps both ways.
Have you tried using ZeroTier? I don‘t have much experience using Tailscale but have been using ZeroTier for two years now without any problems. Runs great on Synology
I'd love to try ZeroTier but sadly, my DS220j doesn't support Docker and therefore ZeroTier. As far as I know they also don't have a package file that I could manually install on my Synology.
on either machine, does
tailscale statusshow your connection passing through a DERP relay? If so, you should investigate why you're going through DERP and try to resolve that.I have no experience with NAS but does it have an HDD? Maybe the read/write speed is the bottleneck. Again take this with a grain of salt since I do not have any experience with running a NAS.
HDD's can actually go a lil beyond 1000Mbps so that's not it :) And at home it does the job just fine
The tailscale guys are very responsive if you send them a question.. It's meant to be P2P but when it can't i believe it uses some kind of relay proxy server so at a guess i'd say it's that. Personally i run a subnet router on my LAN and not on individual devices.. maybe you could try that instead?
Thanks for the tip!
I’ve been trying to set up a subnet router, but can’t seem to be able to get the hang of it. Are there any good tutorials, or tips you could give me? (Sorry to bug you)
Do you get better speeds transferring over Tailscale when both machines are on the same LAN? I have no problems pushing 400mbit over Tailscale but it does use a ton of CPU so maybe the Synology CPU is the bottleneck if you have similar speeds after eliminating your internet connection.
