If you’ve done any Portal version 6.0 development using RAD version 7.0.X, you may feel that there’s a tremendous, robust feature set, but at a cost. The cost is the lengthy time it takes to start and stop the Portal server during development and testing. It can easily take 10 minutes or more for the Portal server to start! While that does offer a convenient time for a coffee break, you might prefer to use your time more productively.
The reason why Portal 6 development using RAD 7 is slower is because, for the first time, RAD 7 includes a full Portal 6 server, rather than a streamlined Portal test environment. Hence you have more capability, but you also have a full Portal 6.0 instance running on your development machine, which can drain your resources.
The following article provides tips on how to reduce the amount of resources that Portal 6.0 consumes on your machine, as well as how to optimize its performance for your development requirements: http://www-128.ibm.com/developerworks/rational/library/07/0327_riordan/
In addition, I have learned that IBM plans to really fix the performance issues in RAD version 7.5 supporting Portal version 6.1 development. Portal 6.1 is due to be released in General Availability by the end of June while RAD 7.5 is estimated to be GA by mid-September 2008. Until then, the performance and optimization tips from the developerWorks article might just shorten your coffee breaks.
