Here is another isolated test:

file size       23746229
eth0 rcv        25491852 (17492 packets)
ppp0 rcv        29191889 (17492 packets)

The above shows packets are reasonably large
close enough to the 1492 mtu.

I ran iptraf to watch traffic and there was no other activity on the

overhead is
	eth0:	25491852/23746229=  +7%
	ppp0:	29191889/23746229= +23%

I say the ppp0 overhead is excessive. Can anyone comment?
Now, the data is highly compresses, so content compression is unlikely.
Header compression is possible, but pppstats does not show any.

my script('fw' is my firewall, 'viewnet' includes the pppstats):


rm viewnet
curl -O http://fw/cgi-bin/viewnet
mv viewnet

curl -O

curl -O http://fw/cgi-bin/viewnet
mv viewnet
