[JBoss-user] [Beginners Corner] - Re: CMP vs. BMP
The optimisation is basically just the caching that the container does. So if you have an application which uses lots of the same data over and over, yes it will be faster. But if you have an app that uses all sorts of different data without much re-use, then there will be no difference. Anyone disagree? The datasource is the same - database & JDBC - so actually the CMP is probably going to be slower, since CMP often makes more calls than you personally would program for any given situation when doing a BMP.

You're quite right Nickman. I didn't mean to change the subject.

[JBoss-user] [Beginners Corner] - Re: CMP vs. BMP
But you did not ask which was most flexible, you asked which was fastest, and for a number of reasons, CMP is nearly always faster than BMP. JBossCMP is also very flexible. I was able to make it support a series of unusual constructs. http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3826504#3826504";>View the original post http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3826504>Reply to the post --- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.

Sorry Loubyansky, I don't quite agree. CMP is fast, but there are times when I can't make CMP do what I want. Some applications require the flexibility of BMP.

I just want to here what other peoples opinion. is that true, that you should always use CMP?
