Does -d64 option for JDK 1.4.0b3 speed up Tomcat at all on Solaris?

I just installed the latest JDK 1.4 beta and noticed that there is now
64-bit support for Solaris. I noticed that there is a -d64 option in the
java command. Does anyone know if this will speed up the performance of
Tomcat at all, or what advantages it offers in that type of environment if
any?
