QNS in Ians webpage

[Shankar Ranganathan]

I went thru the Ian's web page. In the ejb part, I saw some qns related to the performance of BMP and CMP. Is it true that CMP does not give a good performance than BMP.I saw this fact in his page.I got confused because, Sun suggests to use CMP all the time unless otherwise you have a complex queries. Kindly clarify

IMHO
This is an area where EJB goes from science to an
art.
The quality of the container is going to make
a lot of difference. The solution you get
from Oracle, Bea, IBM and JRun could vary
greatly.
I think intuitively the initial thought was BMP would beat CMP. I think real world results are
showing CMP can be very good.
