ZeroTier File Transfer Speed

I've not setup any other VPN between the 2.
No other VPN would likely be useful as all VPNs will have the same general performance. ZeroTier is basically a managed SSL VPN. We can reasonable guess that another VPN will have the same issues. The test you want to do is without a VPN. Only then can you know how much the VPN is cutting down the overall performance. I guarantee that you will find that your direct transfer doesn't come close to 500Mb/s.
Right now you are blaming the VPN for cutting down the performance, but as you don't know what the original performance is, it's impossible to know how much impact the VPN has.

@NashBrydges said in ZeroTier File Transfer Speed:
I wanted to test how fast I could transfer files between the 2 so the short answer to your question is, yes, I'm trying to see what the max speed is that I can get.
That test can only be done by a point to point, non-VPN test.

There could be a router between your two locations on the internet that is the source of the bottleneck.
This is why Scott wants you to use a non-VPN connection to make a speed test.

I totally get that I'm going to face some overhead but I wasn't expecting this. And the encrypting/decrypting activity would translate to higher CPU usage but I'm definitely not seeing anything that tells me CPU is bogged down. CPU usage during file transfer is below 20%. Unless this activity is pegging a single thread meaning I wouldn't see a CPU bottleneck when looking at utilization, I'm not sure this is the issue.
I didn't say CPU bottleneck, I said added latency. Not the same thing. Latency is a guarantee, no amount of the CPU not being pegged over a period of time tells would suggest that there is no latency. Especially as CPU load is measured over a period of seconds. The VPN is absolutely pegging the CPU, all transactions do, the question is for how long. If the VPN did it for enough time to hit 100% for any reasonable measurement period, your speed would be in Kb/s, not Mb/s.

@NashBrydges said in ZeroTier File Transfer Speed:
I'm seeing anywhere between 5ms and 12ms either direction when pinging.
What's the latency difference inside and outside of the tunnel? But keep in mind, the more data that you transfer, the larger the latency will be. A straight ping is slightly misleading.

There are guaranteed to be many, in fact. All of them potential contribute bottlenecks to bandwidth, all have to add latency.

200 Mbps is not bad. I'd be happy with that.
You'll probably find out that the speed will vary a lot from day to day and hour to hour.Best performance will be when you use the same ISP and are physically close.
It's also possible that the ISP will throttle your connection automatically depending on what port/protocol it sees. If so then running on another port sometime gets around that. -

Hmmm...maybe my expectations were too high. I transferred a 1GB test file from the remote PC to my Nextcloud install on Vultr and got around 200Mbps as well.

Assuming you used an SSL cert, then you still have the VPN overhead in that situation. but yeah, likely you are reaching the limit of the connection via the internet.

Nextcloud by default would use SSL, so a VPN connection for all intents and purposes, so a good comparison of another VPN situation.

Check it with
SpeedTest.netand see what you get? -

Check it with
SpeedTest.netand see what you get?that's where he started, that is useless. That's what led him astray in the first place because it shows the speed of the WAN without showing the speed of the path.

True, but that would also confirm his ISP is giving him what he's paying for.

That is not the question. No one cares about that.

I see no mention of how this was verified above, thus the reason I recommended SpeedTest.

So if you're paying for 500 megs and you get 3, you don't care about that?
That should be one of the early questions asked when researching file transfer speeds -- whether a VPN is involved or not.
