And in addition, only tells you the link's theoretical speed, not the
actual speed.  For example, a mobile 'phone on WiFi may notionally have
a 300Mbps link.  But it'd doubtful you'll actually get that speed on any
transfers, even ignoring things like other hops on the route between
device and remote server.

Measure the performance yourself. :)
