How Fast Is The Build And Deployment Of about 660 JPA Entities And 50 Session Beans On Glassfish v2 And Netbeans 6.1? 📎
I'm often asked about the deployment performance of Glassfish v2 in Real World. If you have just few EJB 3 and JPA-Entities the whole build and deployment takes only few (1-3 ) seconds. In Real World you will have rarely only few components to deploy, so I just measured the performance in the one of my current projects. The initial (standard Netbeans) ant build and deployment of JSF application with 660 JPA Entities and about 80 EJB 3 in an EAR, with creation of tables etc. takes:
Enable of application in all targets completed successfully
All operations completed successfully
post-run-deploy:
run-deploy:
BUILD SUCCESSFUL (total time: 2 minutes 32 seconds)
Subsequent redeployments are much faster - and takes about:
Enable of application in all targets completed successfully
All operations completed successfully
post-run-deploy:
run-deploy:
BUILD SUCCESSFUL (total time: 41 seconds)
In both cases the full cycle (clean, build deploy and undeploy) ot the whole EAR was tested. It seems like preparing the named queries and deploying the JPA entities consumes most of the time.
The first deployment in incremental / or activated directory deployment (goto -> services -> Glassfish -> options in Netbeans 6.1). Is very slow:
Enable of application in all targets completed successfully
All operations completed successfully
post-run-deploy:
run-deploy:
BUILD SUCCESSFUL (total time: 7 minutes 6 seconds)
But subsequent deployment become really fast. I changed some JSFs and EJBs and it took:
Browsing: http://localhost:8080/myapp/
run-display-browser:
run-ac:
run:
BUILD SUCCESSFUL (total time: 6 seconds)
opening the browser included :-).
If you like to use the incremental deployment, use the "Run" option in Netbeans, instead of "Undeploy and Deploy".
It was tested on Glassfish v2 (developer profile) on Java 6 update 10, Oracle XE, Netbeans 6.1 ...and Windows Vista 32 bit (without activated virus scanner :-)) on a IBM notebook. However from time to time it seems like Windows locks the files - so I have to restart Glassfish then. It seems to be a Windows problem - it occurs only in the "directory deployment" mode.
