The main reason 2.2.x is so much faster, is the fact the whole filesystem
code has been rewritten from scratch (using the new "dcache" which has
several really nifty new features, including one which sets it apart from
all other unix filesystems, which is the fact you can work out from the
inode number, which file it refers to - which is why you will find for
example that /proc/<pid>/cwd is now a symlink to a real directory rather
than just (eg) [0303]:123456)
The other reason 2.2.x is so much faster, is the fact that the networking
code's been rewritten from scratch (again) and several other important
core functions have been rewritten.

The fact that so much was rewritten is the reason it took them almost 3
years to finish 2.2
