Are there any actual states on SFSB vs HttpSession objects

[kasim]

I was just curious.

I have read and even said myself that SFSB's are as much of a hardship as HttpSession beans. that in EJB2 SFSB's were much worse.

However .... has anyone actually run any stats?? Like comparing JBoss 4 with EJB2.x vs EJB3 vs HttpSession??

thanks
