That's why we don't use getter/setter functions in our CFCs VO (properties are public), so we don't have this performance issue. I suppose it gives you the performance of "struct" and the advantadges of typed/mapped objects. Benoit Hediard #affinitiz.com _____

I made a test where a cfloop is done on 2000 records and had three setups: 1) cfloop / createObject on a CFC "Bean" / add this CFC instance to an Array 2) cfloop / createObject on a JavaBean (same as Erik mentions) / add this bean to an Array 3) cloop / delegate object creation to a Java class (instatiated upfront) / Java class returns JavaBean / add bean to Array 1) is slooooooooooow (like 5000ms) 2) is fast! (like 50ms) 3) is fastest (like 30ms) the difference between 2) and 3) is not significant. But the difference between 1) and 2) is! I think the main problem is that CFC instances are not really comparable to JavaBeans / Valueobjects at runtime because every single method (getter/setter) of a CFC gets compiled into a single class. So a Person.cfc with 20 properties implemented as getters/setters gets compiled into at least 40 classes (one for every getter and one for every setter) plus some more stub code. I think this is the main reason why creating CFC ValueObjects / Beans is so expensive inside loops. IMHO it should not be regarded best practice to use CFCs as VOs - this may work for simple tasks but is definitely not good for more compley setups (e.g. using CFCs to get typed objects in the Flex frontend) Dirk. _____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of EECOLOR Sent: Wednesday, November 22, 2006 2:35 PM To: [email protected] Subject: Re: [flexcoders] ColdFusion and Flex Integration - up to 10x gain, avoid cf object creation Some time ago i experienced with java versions of the value objects. This also gives a significant improvement. Greetz Erik
