Provider with highest throughput between USA and NL
Hi All,
I've noticed that on a couple of VPS's I've used (racknerd, naranjatech) the up/download speeds between a VPS in the Netherlands and one in Dallas, TX, USA is mostly around 32Mbit (around 4 Mb/s) and latency between 100-150 ms. I use this to sync between two servers.
I was wondering if any of you have any experiences with better bandwidth/latency between VPS's that sync between Europe and the USA. It is hard to find this information because 1 or 10 GB network doesn't really tell you this.

Do you already have existing services in these locations? DM me the IPs and I can test the speeds from our servers in the Netherlands and viceversa, I can share the results to see if they suit what you need.
@PureVoltage 🤝
@hosthatch
I do, I will DM you. I'll put a test file on the server first.
Thanks!
@b00n
We got you covered for this good sir!
Speeds to Amsterdam on our 10G servers hit 10g.
Our VPS lineup should do wonders for you as well.

Was just reading through that on an older topic. What I can't tell from there: do you offer a Dallas based VPS on that BF deal? I only see NY on your website.
NY would likely be more optimal for you. Give it a run

I'm sure it will be
but for my use case I need it to be a Dallas (or at least TX) based server.
Dalllas we should have up early Jan for our VPS nodes out there.
Right now just NY which would be the best performance to NL
I've found updating sysctl.conf with the following parameters causes most of my VMs to max out file download/upload speeds between any host US to EU etc.
net.core.default_qdisc=fq
net.ipv4.tcp_congestion_control=bbr
net.core.rmem_max = 134217728
net.core.wmem_max = 134217728
net.ipv4.tcp_rmem = 4096 87380 134217728
net.ipv4.tcp_wmem = 4096 65536 134217728
net.core.netdev_max_backlog = 300000
net.ipv4.tcp_moderate_rcvbuf = 1
net.ipv4.tcp_no_metrics_save = 1
net.ipv4.tcp_mtu_probing = 1
sysctl -p (to apply)

I'd explore sysctl confs with https://tuned-project.org/ profiles.
Interesting, thanks for sharing, I will test this!
This is iperf3 with bbr enabled, run between RackNerd (NYC) and HeartBeat-it (NL).
Dude, you are THE absolute bomb! After applying this to both ends, my servers fly
I now pull in files with 1gbit 
This is something @1gservers had mentioned for using boxes with 10g interfaces. I've found it works for just about any system to max throughput (assuming both ends are set this way).
I have the same issue as @b00n from NL to CA and the main issue is the low speed for 1 single connection.
For example:
If I do a speedtest with yabs or nws script (iperf3) the result is 900mbit/sec on a 1G line for example.
If I upload a single file of 10GB via SFTP it results in only 4mbit/sec. (Bandwidth seems throttled).
If I upload the same file with a VPS in NY as a proxy in between, it hits 100mbit/sec.
Does anyone know if there's a way to upload files with multithreading and encryption on the fly?
Please apply the reply from zorker on both servers and try again. My problem has vanished and it is maxing out now!
Thanks @zorker!
From my experience for example EasyVM in NYC (Telehouse Teleport) has great connectivity towards Europe.
They still have their 75% Black Friday offers on their website (easyvm.net)
iperf3 running on a VPS from EasyVM in NYC, US with Arelion/Telia routing against Leaseweb in AMS, NL resulting in solid 1.5 Gbps per tcp flow in both directions and only 75 ms RTT.

SFTP has a lot of CPU overhead and SSH in general doesn't like higher latencies. You might be better off using rclone over HTTPS/Webdav. I actually run ZeroTier combined with Rclone/Webdav over HTTP to move files from EU to US with full 1g speeds.
rclone, 100%
Transfer test from NL (HeartBeat-IT) to Dallas (EasyVM):

what actually does this do?
I don't honestly know. I just see the results. 1Gservers posted it a long time ago and they didn't know where they found it either. I'm surprised more LG servers don't do this. I found an LG in Taiwan that I can pull 3-5Gbps from to the US.
Should also mention if you need a test site, hit up 1Gservers LG https://1gservers.com/network.html and do a before and after test
It's so incredible, it's like magic.. 😀
The important one that's kind of ridiculously big is
net.core.netdev_max_backlog = 300000, and it's the number of packets that can be in flight before blocking. It's normally 1000. This change makes that absolutely massive, and could probably cause you to end up consuming a massive amount of memory when there's significant packet loss.It's probably more sensible to set it to something more like 65536 (about 96MB maximum) rather than the potentially half GB this example could consume.
