Scaleway bandwidth performance
I'm a bit confused about Scaleway network perfomance.
I prefer to use IPERF to test network performance (instead of WGET). As a client, Scaleway does fairly good with some 500 Mbps/s peaks both to OVH or Online.
The story changes when I use the Scaleway instance as an IPERF server.
Results 1 (SERVER: Scaleway - CLIENT: OVH VPS):
Results 2 (SERVER: Scaleway - CLIENT: Online, Kidéchire):
In the same network (Online --> Online), as expected, Scaleway performs good. Can't say the same when I used OVH.
Now, do you experience the same? If you have the possibility, can you perform some tests so that I can see if this is an isolated case?
This is the command I used:
iperf -c IP_SERVER -t 10 -i 1 -w 500 -P 5 | grep SUM
To launch IPERF as a server, type:
iperf -s
Thanks!

Thank you for your information. I'm looking for ScaleWay reviews.
Some nodes are located on racks full of seedboxes, so, if you get bad network results just keep creating instances until you get a instance on a rack without so many torrent downloaders.
I don't have anything with OVH, so did this on my QPS dedi and of course, Scaleway:
Results 1 (SERVER: QPS - CLIENT: Scaleway):
Results 2 (SERVER: Scaleway - CLIENT: QPS):
Also, speedtest.net result (hosted by Online itself) also suggest not so good upload speed:
Hope this helps.
Thanks @emdad.
Scaleway has decent download, but not so much upload. Yes, the price is cheap, but one expects what's advertised (or at least not 1/4 of it).
Drop a ticket to the support with your complaints and ask for your rights. They should maybe move you for another rack.
I will, thanks
Maybe @OnlineJulien or @bene_online could explain these bad speeds on sw. I do had servers with low speeds like those too.
Or also @mikmak .
Lol, "servers" with 10x better download than upload performance ... riiiight.
Please run iperf (preferably iperf3) with 1 thread on 1 minute with 10 seconds interval. Do not force the TCP Window size, the kernel will handle that.
iperf -c $host -P1 -t 60 -i 10
Use online's iperf server, I was getting 6Gbps from Atlanta to it the other night.
Then you can see whether it is a local network issue.
Here's a Quadranet (in Dallas) VPS using online.net (I just ran the command from that iperf test thread a few months ago)

Ok I tried the command that UrDN suggested instead and used my Dedibox to online.net for this one
root@dedibox:~# iperf -c ping.online.net -P1 -t 60 -i 10

This is using my scaleway instance as server and another vps (with high download speed) as client:
Can you try downloading http://ipv4.rbx.proof.ovh.net/files/10Gio.dat for a few minutes and report the average throughput?
This speed....
Is it worthy to switch my KS-3 to this (with additional storage) for torrenting?
The bandwidth between two of my scaleway nodes is ~110M bytes/s so 880M bits per sec:
Scaleway -> a linode in London gets next to nothing:
I don't mind because I'm doing cluster computing but it certainly doesn't look good for those of you running web servers. That said, it looks as if they have an outage at the moment so this probably isn't normal. I haven't been with them for long enough to know what is normal.
Some racks do have por network performance because of tons of seedboxes running on it, but 30/40 mbps isn't normal of course. If you get network speeds that low you should contact the support. Premium bandwidth, on the other hand, is perfect every time.
some of these stats looks strange to me,
what we would need to help debug and improve this :
"mtr -rwc 120 a.b.c.d" in both directions (Really, this matters) with both IP src and destinations (so we can reproduce)
iperf on your scaleway server that shows problem
same iperf on ping.online.net
afaict I see no single scaleway chassis filling its uplinks, so the idea that "many seedboxes in one chassis" that would sature something is not the problem here
thank you all
Mik
Sorry if I answer so late:
Which is pretty good. However, I'm more interested in upload speeds.
