OVHCloud Network Speedtest


[link to this post]
 
https://proof.ovh.net/

Has anyone noticed it? They changed new layout website as it now much worsen than before!

Getting wrong speed as it use to be very accurate speed test spot on every time from old layout but not anymore.

Mine was getting

Server
🇬🇧 Erith
Download
374.1 Mbps
Upload
107.6 Mbps
Ping
10 ms

Before the old one was 931.2Mbps / 108.1Mbps 10ms

Why and what have you done OVHCloud?

Like fish in the sea, there are plenty of other speed tests servers available. Why should this trouble you so much?

To be fair OVH was one of the most accurate there was, and they've broken their own system. If someone wants to comment Pheasant, it doesn't need you to pipe up to antagonise does it?

Really? I was never impressed by any of the OVH test servers, in the past or now. Erith looks like their only British based site and the French sites deliver fairly meaningless / non indicative results. OpenSpeedTest is also hampered by browser limits. It' just a bit rubbish

To get a better indication use iperf3 from the command line/terminal on a wired machine.

Try these on for size...should give a much better indicator of off-net and transit performance than OVH....

iperf3 -c iperf.as42831.net -p 5300-5400 -R -P 8 -t 20
iperf3 -c speedtest.lon1.uk.leaseweb.net -p 5202-5210 -R -P 8 -t 20
iperf3 -c speedtest.lon12.uk.leaseweb.net -p 5201-5210 -R -P 8 -t 20
iperf3 -c speedtest2.lightningfibre.net.uk -p 4000-4007 -R -P 8 -t 20

Have you considered the possibility that what the speed tester is telling you is true: there is a limiting factor somewhere along the Internet path between your client device and the OVH speed test server. It's an end-to-end test so you're testing everything in between. Small levels of packet loss anywhere along the path can limit the rate at which TCP sends traffic: the formula is here.

If you get full speed to other speed test sites elsewhere on the Internet, then that probably rules out a problem at your side. But that begs the question: unless you intend to make use of a service hosted at OVH, why do you care about the quality of the Internet path to OVH?

TBH, I don't really understand why people are so keen on constantly speed testing their broadband connections. Just use it. If you observe a problem, then doing tests may help isolate the problem and provide useful information to your ISP when you report the issue. But otherwise, you're just adding to Internet congestion.

I do wonder what motorway congestion would be like if everyone kept driving back and forth to Barnard Castle just to check their car and their eyesight smile

Well there's checking your car....and then there's "checking your car" (...can reach its maximum design speed) on a regular basis.

At some point you're going to get into a spot of bother with the law attempting that. Irrespective of errr eyesight checks Mr C 😂

Back to OVH and their OpenSpeedTest page; (re)loading the tester between tests is definitely flaky and the test results are widely variable. For example I managed to get it around about full stated line rate, as follows but other OST tests were wildly different:

OVHcloud network speed test — lon1-eri.speedtest.network.ovh.net
Server: 🇬🇧 Erith (lon1-eri.speedtest.network.ovh.net)
Download: 4740.4 Mbps
Upload: 5592 Mbps
Ping: 1 ms
Jitter: 0 ms
Network: AS25160 · Vorboss Limited
2026-09-29 17:12 UTC
https://lon1-eri.speedtest.network.ovh.net/

Running via iperf3 with 8 parallels flows, I was able push the upload to 8.63 Gbps with fairly minimal retries on a 20 second run. Download was pegged around 4.82 Gbps but the retries were much higher. Presumably this is their 5 Gbps policer enforcing the limit.

Single flow tests give upload at 7.83 Gbps (again minimal retries) and download on single flow is identical to 8 x parallel flows at 4.82 Gbps. Again policer in action.

I would urge Max to run his speed tests using iperf3 rather than OST on this site.
