user-ppp faster then pppd ?

[humbaba at gmx.net]

Hi
I recently tried to connect to the Internet using kernel ppp (pppd) instead
off user ppp. I noticed that the connection was about 0.5 KB slower whith
pppd when downloading the same file from the same server. I'm using a 56 K
modem and have Release 5.1 installed,  I also appended my /etc/ppp/options,
ppp.conf files.
What could be the reason for the different throughputs?
