RRC is a performance nightmare.

Hi John,

If you have specific issues you are experiencing please let us know about them and we'll be happy to work with you to get them resolved.

There are many factors that contribute to performance issues and we are continuously working to address them. We are fully aware that there is always room for more improvement.

Hi John,

I don't know wheter you are using Tomcat or WebSphere but I highly recommend to use WebSphere. There's a very big difference between app servers performance. And Hardware specification is important too.

I am using RRC with 8 core and 16GB ram with a WebSphere App Server and seems to have no problem.

But I also believe that editing graphical artifacts was much more easier with Rich Client. Activating the RRC Add-On and editing graphical object is slower than RRC 2.x.

Working on diagrams and so on, or any complex structure with a web client does not make sens to me.

I believe we need both a web and an heavy client..... it is the same for tests.

Integration between requirements and architecture is also a key point. We want to allocate requirements to systems / subsystems and architectures components and to trace to UML model elements.

We need an integrated environment (requirements/architecture/development). It is not just linking things....it is not just traceability... it is also providing views and tools to do analysis efficiently.

I would be surprised that a full web product could address these needs.

Agreed, there are times where for some projects both a web and rich client are needed.

Rational DOORS Next Generation will build on the heritage of Rational DOORS and extend the technology base of Rational Requirements Composer (web client and server) and Rational DOORS 9 (rich client).

RRC is a performance nightmare. Stef when are you going to stop blowing smoke up peoples butts and finally admit what a crappy tool this really is?

As others have mentioned, it would be great if you could be a little less emotive and a lot more specific in detailing your performance issues :-)

Having said that, I have found that nearly all of my clients who are just starting out and are having noticeable performance issues with any of the Jazz tools are using IE and are being bitten by the well known IE JavaScript engine problems documented elsewhere, which include horrible performance and memory leaks.

If possible, could you try your RRC environment using both Firefox and IE to see if the problems are browser related or server related - that would be a good first step.

I was told that RRC was more stable in IE...sadly, than in Firefox or Chrome. Due to the unstable support of the graphic editors in the others.

In RRC V3.0.1 IE8 is better than IE7, with the graphic editors, in both performance and stability.

Now personally I find FF 3.6.x to have better performance and less problems than IE8. FF also supports drag and drop of multiple files.

Is FireFox 10.0 supported?

FF 10 is not yet officially supported. FF 10 ESR will be supported for the 4.0 release and we are working to try and add support for it in the upcoming 3.0.1.3 release, so stay tuned.
