[JBoss-user] CMP/BMP Performance
Hi All, I'm about to start implementation of a fairly large system, where performance is a big issure. Can any one give me a tip on what road I should select. Should I choose CMP, BMP or make a DAO layer where I'm using JDBC? Hope you can give me a hint :-) Cheers Jan --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

This is an interesting and informative article about that very topic: http://www.urbancode.com/projects/ejbbenchmark/testsAndResults.jsp Good luck, Ben NIELSEN JAN, Teliadk wrote: Hi All, I'm about to start implementation of a fairly large system, where performance is a big issure.

Re: [JBoss-user] CMP/BMP Performance
Jan, Use CMP2. Write load tests so you can measure performance. Then, you can optimise loading by changing the jbosscmp-jdbc.xml files. Look up the documentation on it. Run your tests again. See if you've improved performance. If you don't measure performance, you can't tell if what you are doing is fast or slow. If this is still too slow, you can always write some direct JDBC or use BMP.
