It's from my GNU/Linux box, yes.

crash@isengard:~$ sudo ping -f
PING ( 56 data bytes
--- ping statistics ---
167242 packets transmitted, 167212 packets received, 0% packet loss
round-trip min/avg/max = 0.7/6.3/50.9 ms

I can't reboot the Hurd box to GNUmach2 right now since I'm at work,
but I can follow up on this thread tonight if someone is interested.

The Hurd box has a 3Com 3c905B Cyclone 100baseTx and the Linux box
has a NE2000 10baseT, so that might have something to do with my
results. But still, the results are worse in GNUmach2 right now.
