I am migrating a rather large application from J++ to J#. It has a
multi-tiered architecture and depends heavily on Java serialization for
moving data beetween server and clients. However, the Java serialization,
using java.io.ObjectOutputStream and java.io.ObjectInputStream is about 5
times(!!!) slower in J# compared to J++ and this fact is jeopardizing the
whole migration project. How can it be so slow? Is it the .NET Reflection
system that is much slower or what?
