Yes, I disabled gso and tso on vanilla 2.6.27-rc7 via ethtools and
got the same results:
$ sudo ethtool -k lo
Offload parameters for lo:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp segmentation offload: off
udp fragmentation offload: off
generic segmentation offload: off
1 proc: 195 mb
