[rules-users] Should I use drools for this application ?

Hi , I am using Drools version 4.0.4 I have an application which fetches data from a database. Each row from the db is stored in a domain object and these objects are inserted into arraylists depending on a specific id. Then I insert the arraylist into the rule engine , the output required is the selection of one object from the arraylist and putting it into a global arraylist. I have tested this application with about 2500 rows . It takes 7 secs . Also I have tested this application without using a rule engine , I wrote business logic in my code . It took me 5 seconds . One point that I need to be clarified is can we except performance improvement by using drools ? Can I derive a conclusion from this excerise , that this application is not to be used with drools or is there something that I am doing wrong . Also is there some document which can tell me where and when to exactly use drools ? Thanks a ton Harsh Jetlyharsh.jetly(a)lntinfotech.com -- View this message in context: http://www.nabble.com/Should-I-use-drools-for-this-application---tp188495...
