The performance claim has not been true for some time,  I think as far 
back as 2.4.

I have no problem with how swap behaves, I simply have no need for swap 
at all on some of my systems.

Ponder a SOHO environment, which is the kind of setup I handle these 
days. If a Pentium IV with 1 Gbyte of RAM and 2 Gbytes of swap will do 
the job, how much better would a system based on intel (or equivalent 
from AMD) i5 and 4 Gbytes of RAM do the same job.

RAM for a typical SOHO system costs less than the time to acquire it and 
install it. The difference in cost is simply not relevant.
