No, type 4 driver will never outperform the InterClient simply
because the network traffic is higher. Also, add some time to prepare
all data for API calls, that are done in InterServer on native level,
and you will understand that type 4 cannot be faster than IC.

Problems with IC are:

1) it is not under development, so you have a 2-year old code (IC 2.5
cannot be taken into account, because you have to buy IB 6.5)

2) you have only 3 deployment platforms for InterServer (Windows,
Linux and Solaris), and InterServer has to run on the same host as
database does.

But type 4 driver should not be so slow. Or, more correctly, it
should be as fast as InterClient if the amount of data transferred
over the wire is much more bigger than request data.
