How to Speed Up IBM Rational Application Developer/Rational Software Architect
I want to know how can I speed up RSA 7.5( which is an IDE by IBM having eclipse under the hood with websphere server runtimes) mainly server start. The first time I start it after computer reboot it loads after, but after that it takes for ever to start/stop the server. The debug mode for server takes for ever to start.
I am using server 7 run time for IBM RSA 7.5.
So bascially RAD/RSA has websphere run times which allows to configure the server runtime start/stop within RAD/RSA. The run time allows you to develop webapps and test time on the server on deploy it on the websphere run time.
The problem I am facing is with the websphere runtime which works fine after computer reboot but is very slow after several deployments/publishing of the same web app.
I would be grateful you give performance tips for speed up RSA server start/shutdown and overall performance tips. I have plenty of memory like 12 GB with i7 Core 6 cores on Win7.
Answer
Of course of your are running the server in debug mode it's going to be a lot slower, but you have a few options like putting the server in development mode or doing some fine tuning as to which applications should start. Take a look at these articles:
- Rational Application Developer Performance Tips- Case study: Tuning WebSphere Application Server V7 and V8 for performance
- Performance tuning WebSphere Application Server 7 on AIX 6.1
- WebSphere tuning for the impatient: How to get 80% of the performance improvement with 20% of the effort
- WebSphere Performance Monitoring & Tuning
Some of these are a bit dated but they have some good information that may still be relevent to your issues; especially the first one.
