Not true.

With my patches and LTO Linux can be competive with LWIP+socket layer.
(about 60K more text). And it's easier to use because it's just
the standard interface.

Linux has always been a system from very small to big.
That's been one of its strengths. It is very adaptable.

Many subsystems are very configurable for this.
For example that is why we have both SLOB and SLUB.
That is why we have NOMMU MM and lots of other tuning 
knobs for small systems.

So if the other subsystems can do this, why should it be
impossible for networking?
