Object serialization and session

[nick]

Hi,

I have a User object with properties ID, FirstName, LastName, and an
array of Permissions which I would like to keep in session. Should I
first serialize it to put it in session? I read that this is not
necessary, but I'm wondering about memory usage and performance. I
realize that serializing/deserializing the object will take time, but
will the serialized object consume less memory than the non serialized
object? If so, will it be significant. Thanks.
