Determine real bandwidth usage

[dobledosis]

Hi, i need to determine my real bandwidth usage in windows, but i find discrepancies when comparing different methods.

Cacti says im using 3Mbps I/O:

Net Limiter says aim using 2Mbps I/O

Resource monitor says im using 2Mbps I/O

Task manager says im using 3% of 100Mbps = 3Mbps I/O (I think so)

This differences increases and are more noticeable when bandwidth usage increases. Which method should i trust and why this differences?

Thank you!

This should be quite normal.
Speed test is just a guide, and it depend on which server the speed test use.
Also it depend as not only you are using, many others are also accessing the network.
There is no such REAL Bandwidth.

Windows (task Manager/ Resource manager Etc), actually show the speed of your LAN not your internet connection so the figure you are getting is the same as the others, there will always be minor variations due to local and systemic reasons the best thing to do to ensure a reliable figure for your system is to always use one and only one measure.

The one the vast majority of forum users recommend and therefore a sort of forum standard is Speedtest.net by Ookla - The Global Broadband Speed Test - let the system pick the best server for your setup (and you can keep a record if you sign up for free )

There is a thread on this forum that shows what others are getting ...

I never said that i want to know my internet speed... I want to know exactly the bandwidth that a connection is using and that i don't know why if i use 4 different tools they give me different results. In the exaple i gave theres only 1Mbps I/O of difference, but as bandwith usage increases, that difference increases even more, for example last night i had 14Mbps I/O with Cacti and task manager, and 10Mbps with Net limiter and Resource monitor.

Download speed depends on where you are downloading from eg I may get 62 Mb/s d/l from Microsoft, but only 0.5 Mb/s from a dodgy movie site. Ditto upload - I get 18 Mb/s u/l to Vimeo, but only 8 Mbps when u/l to Dropbox.

I concur with Barman58 - measure max speed at speedtest.net. Addgadgets have a good realtime desktop network gadget -

More information about bandwidth that I and maybe others might not want to know.
It does get complicated.

I find using a 3rd party firmware, such as tomato, on my router gives me the best stats on bandwidth usage.

Someone may have said this or maybe it's not what you are asking. If so.. sorry.
