The primary benifit comes when the type 2 mode allows the java app to
make
use of a more efficent local ipc method(although currently at least
for
windows the implementation has drawbacks too) or in the case of the
embeded
server - no ipc method at all. This can under some circumastances(eg
running
many individual but small fast querys) lead to almost doubling of
performance.

I found when doing some benchmarking that type 2 mode when making a
tcp/ip
connection to the server is actually slower then in type 4 mode
overall.
