How can I verify my ISP internet speed?

[Rob Lahaye]

Hi,

I have my FreeBSD PC connected to the internet via ADSL with PPPoE.
My ISP claims my speed is 2 Mbs. Is there a reliable command on my FreeBSD system
to double check the internet speed?

I ask this, because when I complain, the answer is always that the reason for
slow network is due to the slow response of the sites I access. Is this situation
I find it difficult to verify who is right.

Thanks,
Rob.
