We are getting ready to release an OSGI application into production. What are some suggestions/recommendations for Virgo performance tuning?

Please see Virgo's profiling page. Smile

Glyn, thanks for the quick reply. I may not have been clear in my request. I think you are referring to profiling/tuning of the application. I was more interested in tuning parameters for the Virgo server.

Hi Paul,

Can you please provide more details on what your application uses in terms of technology and infrastructure?

For example if you use JSPs as I saw from your other thread perhaps its worth taking a look at some Tomcat performance guides.

How dynamic is your application? Do you expect to have different modules come and go often or you have more or less a static setup?

Regards,
Hristo Iliev

Hi Hristo,

The application is mostly static - no reloading once the PAR is started. It is a PAR that contains multiple bundles and has external bundle dependencies. The technology stack includes: Spring 3.0.4, Spring Security, Spring MVC, Spring WS, JSPs, Tiles, Dozer, and Hibernate.

Thanks,
Paul

Since you don't need reloading I guess most of the performance settings should come from the technology stack components that you are using - Spring, JSP ...

Currently there aren't much settings you can play with. I believe that "productive mode" support is a major scenario that has to be covered so feel free to raise an enhancement request for any additional tuning parameters that will make your life easier.
