Fast.com Speedtest

I notice when using Fast.com that on my 350mb package it very rarely goes above 240mbps. When testing via speedtest (on single thread) I get the full speed (380mbps). If I connect to a VPN i get the full speed via fast.com when utilising a UK server.

Any ideas why this might be happening? At first I thought this might be down to the number of connections, however speedtest works at he maximum speed on single thread and with fast.com working via VPN seems quite strange.

Does anyone else get this issue?

i have just tried fast.com and get 210 nperf.com i get 560 speedtest i get 450, thinkbroardband i get 465

so i guess its a fast.com issue ???

I easily see 500 Mbps or faster on 5G using my phone in big towns and ciites, and over 300 at home on my local 4G.

My Virgin connection is M200 and I easily get between 200 and 220 using fast.com

If yours is maxing out at 240 perhaps something else is affecting the browser you are using. E.g. some security add on?

Nah, it’s not addons as it does exactly same on phone, tablets, PC’s and Mac.

Like I say, it’s not that the connection can’t achieve its max speed, it’ll do it all day long via other testers (even single threaded).

I always trust this site - samknows speed test as it very reliable and accurate spot on.

That's funny. This tester reports a faster download than my Samknows whitebox has ever recorded!

something odd with the test there,I am on virgin 350mb and get around 380mb on speedtest.net and here but fast.com is showing 660mb!

The samknows one reported a peak of 32Mbps upload (during the test), which is a bit suspect as the line is syncing at 18339 (Kbps). Test completed it shows 18.9Mbps. Ho hum.

Watch out for browser caching, I always use a Private / Incognito tab.

I downloaded a file from Nvidia at 67MB/s but only get 380mbs on fast.com so its deffo that.
