FTTC Speed when downloading.

I am on FTTC and am connected at approx 28Mbps download speed.

Yet when downloading from You Tube, the download speed I get is a steady 3.5Mbps, Is this because You Tube restricts the max download speed ? or are there other reasons ?

I use Firefox , and download using Download Helper

Thank You

Is it 3.5Mbps (Megabits per second), or 3.5MBps (MegaBytes per second)? A Byte is 8 bits, and data transfer speeds are measured/shown in MBps by most downloaders.

Just that 3.5 x 8 = 28, which is a bit of a coincidence, and if it is MegaBytes an excellent throughput for your sync .

The Samknows box does bitrate tests of Youtube automatically on my 45Mbps connection. It never goes above 4Mbps. Netflix will go to 15.6Mbps. So, I suspect most Youtube videos are a compressed HD hence the lower rates. You could try finding some Youtube UHD video and see if that streams any faster although I'm not sure if Youtube adjusts the stream quality according to the output device - if it does then your monitor resolution may stop it from trying to stream at higher rates.

Sorry RobertoS , I replied yesterday but the reply hasn't shown up. Probably my error.

Speed shows as 3.5MB/s in the download window, and after reading your post re Mbps versus MBps I now understand that my speed equates to what my actual connection speed from the cabinet is.
Thanks once again.

A very frequent mistake that people make. Don't worry that you did .

At least you now know it is fine. Which is better than not asking, and worrying. Or even raising a fault with your ISP.
