OK I'll have to try that later. It's quite a while since I did a Linux
traceroute but I don't recall it being particularly fast.

I suppose you know that traditional Unix/Linux traceroute sends UDP packets
to (assumed) unused ports, whereas Windows tracert sends ICMP Echo packets.
However, I don't see how that would account for a speed difference.
