There might be contention on the connection between some ISP. That is why the ISP wants you to always test with THEIR speedtest server. Generally you get the best performance when the serer is on the same ISP as you. You will find that different servers can be on different ISP networks. Now some of this is related to how different ISP are connected. You will see that the ping time is more or less the same so the server really are located near each other but you get huge difference in performance. Find a city near you on the speedtest site and then change the server manually a few times. You can see speedtest is affected by the server itself just by changing servers within the same city. So, MY internet speed is great, South Koreas is great, but what on earth is going on in between, and can I fix it? Now south korea has the worlds best internet (standard 25mb for residential) I am most interested in south korea (I am a dentist and the only thing I really care about is getting good access to here). But, after that, does it depend on the server I am downloading from? Obviously my internet speed from my computer to somewhere is brilliant, at 95mb.

Whistle out (tests australian speed) 95 download, no upload speed I then went to and tested all of the countries listed. This was from a server somewhere, and the following test results are from a few minutes after the download finished. I just downloaded a 500mb file, at 500kb/s, about 2% of the. Sometimes, when downloading, it is atrociouis. It is a business connections, so it is the most stable, and they will slow down residential people before me. In australia here, and Ihave the best internet I can currently buy (cant get 5g yet)
