Inaccurate Speedtest?

PS4 not using the right abbreviation for megabits (Mb) vs megabytes (MB)?

It cannot be that case

Why not? Let's say your home Internet speed is 100 megabits per second. 12MB/s would imply that you're exceeding the speed of your Internet service, so either your Internet service is faster than you expect or the indicated speed is incorrect.

Another option is that your Internet is actually capable of 12-15MBps (120-150Mbps) downloads but the PS4 browser sucks so it can only manage 34Mbps on Ookla.

Speed tests are also not 100% reliable. Some types of download can go faster than others, especially if P2P is involved. I can pull over 400Mbps through bittorrent even though my speed tests often cap out at 200-300Mbps.

You're right man. I know now what you're trying to say. Another thing, when I'm streaming 4K on my TV (5GHz) it's always smooth no buffering at all and Speedtest on TV's browser shows 20Mbps. Obviously can't stream 4K without buffering at that speed. So I guess TV's browser sucks as well?

Purpose-built hardware. PS4 is made to play games. TV is made to play videos. Ancillary applications like web browsers often do not get CPU priority nor are they optimized. They'd rather spend money making sure that the primary application (streaming 4K video) works perfectly instead of making sure the web browser is fast.

Tried on my laptop. Get around 40 Mbps on Ookla and download speeds are around 4 MB/s. Although my laptop is 4 year old and isn't very powerful. Could it be that laptop is also not capable getting higher speeds?

level 7

I dunno, there are a lot of variables involved. Wired or wireless? How fast is the HDD? How much RAM? There are a lot of things that can limit download speeds in different situations.

Wireless 2.4GHz, 1TB HDD 4GB RAM, Windows 8. Sometimes it does show over 90Mbps but that's very rare though.

level 9

2.4GHz maxes out at 54Mbps per channel, so I'm surprised you're even getting 40Mbps. Might hit 100Mbps if your hardware supports channel bonding. Wireless is very sensitive to interference and other traffic on the network; it is a shared medium so if two devices are downloading their speed is halved. Basically, don't use wireless for speed tests.

I see. Thank you very much man, your explanation was on point. Everything is clear now. Appreciate your effort!

I have 100Mbps plan and always get around 30-40 Mbps on speedtest. But download speeds on PS4 are great and 4K streaming also works fine but was just wondering why speedtest shows low speeds

Well seeing as how its every 8 megabits to 1 megabyte and you wrote MB instead of Mb, it most certainly can be unless someone is lying. Then there is also overhead and transmission medium and the server you pick.

So either you have your units mixed up or someone is experiencing super lag.

I'm not mistaken man, download speeds are clearly 12-15MB and speeds shown in Ookla are clearly in Mb

Seeing as how the networking world is measured in bits, you need to convert those units. Even your ISP uses bits. Not bytes unless your ISP is weird.

My problem is that even though the speeds shown in Ookla are low, I get higher actual download speeds. Let's say I get avg of 10MB/s which translates to 80Mbps but it would show 30-40 Mbps

level 1

ISPs commonly implement a caching layer for frequently accessed static content. Atop the list of cached content are OS updates and Console games. It is quite common for a game console to download games / updates significantly faster than the Internet service you pay for. Perhaps this is what you're seeing?

Likewise, a speedtest isn't cached so it is a more realistic picture of your bandwidth. It's important to note, however, that most ISPs host a speedtest server in their network which makes it a link-test, not an "Internet" test. For the most realistic results you need to explicitly select a server in a different ISP's network.

tried a different server, still not a difference. And also weird thing is that I get higher upload speeds than download speeds lol

level 3

Do you have broadband service? Or is your Internet through the phone company?

Broadband Service
