Speed doesn't matter, but packet loss and latency does.
People are surprised that I have the smallest fiber package (150Mb/150Mb and it's more than enough) and I have "better" internet than their gigabit cable.

As for packet loss, this would be a problem as it means hw issues or misconfiguration somewhere.
