linux 2.6.32 and 2.6.26 nat with pppoe throughput is very different.

[sung descent <descent0@xxxxxxxxx>]

Dear all,
I use debian to do NAT and use PPPoE for WAN side.
3 PCs, one for pppoe server, one for NAT+PPPoE  client (WAN), one for
normal used.

test direction:
pc -> debian(nat+pppoe (WAN)) -> pppoe server

I use iperf to test the throughput:

debian kernel | iperf throughput
2.6.26           | 180 Mbits/sec
2.6.32           | 48.7 Mbits/sec

iperf version: 2.0.2

Can I do any improvement to get better throughput?
