speedtests

does a speedtest only test the line speed ie capacity of line and bear no actual eference to actual download speeds achievable.

I have just done a speedtest and it took 40 seconds to download 200 mb by my arithmetic that's 5mbps but test says it's 43mbps 200/43= 4.65 seconds.

Why the discrepancy?

Hi @RJDSMITH14 The result you're getting is pretty much correct, when you consider that 1 byte = 8 bits, on a 100Mbps (megabits per sec) theoretical speed you could download 12.5MB/s (megabytes per sec) so your 43Mbps equates to 5.375MB/s so 200MB would take around 40 seconds to download.

 

What you're seeing is the 8x difference between megabyte and megabit.

At last an explanation. Well that makes the whole NBN a bigger con. It is promoted using terms nobody will understand. I have some training in network support and I was misled by mbps thinking it was megabytes.

Hi @RJDSMITH14,

 

Just an additional information.

 

Mbps (small "b") stands for Megabit per second, while MBps (capital "B") stands for Megabyte per second.

 

Kind regards,
