ZeroTier File Transfer Speed

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? -

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.

@dafyre said in ZeroTier File Transfer Speed:
it's not relevant. it was tested and known that the line speed is valid.

I can't speak for any other ISP, but Cox only guarantees the speed to their own services. So you buy 500 mbit/s, they only care if you get that to their own internal test site.
Granted, in most cases you should get something pretty damned close to one of the generic testing sites as well - which we assume the OP did when he said he tested multiple times.
With that out of the way - the OP still needs to test a non encrypted transfer via the internet between these two sites to see what that transfer speed is like. This could be done by hosting a HTTP server at either side and pulling pushing a largish file.... then compare those speeds to the VPN speeds...
