there are very many good reasons why this for linux is not the right solution, including the fact that the linux tcp/ip stack already is quite fast so the "gains" achieved aren't that stellar as the gains you get when comparing to windows.
Also these types of solution always add quite a bit of overhead to connection setup/teardown making it actually a *loss* for the "many short connections" types of workloads. Now guess which things certain benchmarks use, and guess what real world servers do :)
