Per connection. Perhaps less than 5%. Your premise that you can't have your cake and eat it too is much more of a matter of a lack of design foresight than fact. There are clearly solutions which address both the functional and performance issues. The benefits of pppij can be integrated into a kernel ppp with gains rather than losses of overall appeal. And your concept of how much memory it takes to implement it indicates you're either very young or very inexperienced...as even the semi-old like myself remember doing fairly powerful things in tiny bits of memory...if you just spend a little time thinking about it.
