How to check connection bandwidth of a server

Hello, I recently hired a Windows VPS server hosted in Germany. The contracted plan has unlimited traffic and 1Gbit/s connection. I want to use this server for streaming videos, so the connection band is important to me.

However, if I connect remotely on the machine and test the connection speed of www.speedtest.net, selecting a server nearby in Germany ping is very low and the download and upload speed reaches more than 500 Mbps, but if I choose a city in São Paulo, ping is higher than 200 and the download and upload speed drops to 11 Mbps.

In 11mbps upload theory will not support even 20 simultaneous connections to videos.

Am I doing this right? Is that really how I measure the bandwidth of a server? Or what I did just determines the bandwidth available to a single customer in sao paulo?

Is there any tool I can do this check?

Thank you.

  • I’m not an expert on the subject, nor do I come close to it, but did you take into consideration that 1Gbit/s is just the nominal speed? The actual speed (download/upload) would be up to 128Mbp/s, without taking into account the priority between download, upload and also the priority that your server has on the DC network. After all this, there is still the question that, an upload or download from Alemanhã to SP, will go through several servers to reach the destination, and to each server that it passes, lower the speed. For streaming, you must use a good CDN, or even with a good connection, your server

Well come on, speaking as experience of who also has a link of 1Gbps, my link is in Brazil same, but use these online speed testers for a link as ours is very complicated, First you will not have guarantees that the link used for the test will also be 1Gbps or that the server board that does this test is a giga network card as well. No use the link being 1Gbps and the server is connected by a network card to 100Mbps. The test you did and reached 11Mbps seems to be one of these cases where the speed was limited by the server network interface used to test the link speed.

I particularly prefer to go up an http or ftp on the target server put a giant iso in there and go on another 1gb link (then you have to see if you have another giga link or some friend who has what is rare rsrs) and download this file to check the speed, clear beyond the link being giga the computer/notebook network interface also needs to be giga and be connected to giga directly on the router or switch to ensure that there is no limitation, to upload you can try to put via ftp and see what speed arrives.

That is if you need guarantees and know the real speed, in addition to your link of 1Gbps you will need one more giga link to be able to do the tests.

  • Cool... the board I have installed is 1Gbps same... but with regard to the upload speed to a server there be so much higher than the upload speed to a server from here in Brazil, That means I may never be able to use the whole band of that board because of the distance?

  • This has nothing to do with distance, it has to do exclusively with source link + source server interface.
