Have you also looked at your value for 'asycmap' for pppd?

If you don't set it, then all control characters sent to you are
escaped.
(This is all characters from 0x00 to 0x1f).  Basically this means that 
whenever a character in this range is sent to you, then it is actually
converted to two characters for transmission.

Try using 'asyncmap 0x00' on your pppd command (or in /etc/ppp/options).

This alone should get you a saving of around 11%.
