Hi Aaron.
I don't have any real life example with OJB. I worked in the design and developing of a server written in Java that handled a very heavy load and has a complex data model, it was mounted in a Solaris/sparc machine with Informix. We used object locks, caches and many features that OJB include but homemade. We didn't knew that OJB existed and I doubt OJB in that time was ready for production. The key for success in performance was to improve the design. The cache and precalculated results were very important for performance.
On the other hand I am writing a similar software that will use OJB. I have done preliminary tests and I can say that the basics features of OJB behave well for large loads of work. The jdbc driver and the RDBMS have a very important role in performance and stability, and are often underestimated. But the design of the application is paramount for performance and stability. In synthesis I think that OJB can do if you don't try the complex or untested features. I think that in the future, OJB will be very stable an apt for that kind of applications.

Do you have any examples of projects you've seen/worked on?you
i.e.: Using Oracle, widgets.com easily handles 500,000 requests an hour
I'm actually not that concerned about using OJB for my current project.... the load isn't that large. But I would like to know the limits of the technology.

It will depends largely on which RDBMS you use, and which OJB features
use. I think all the basics features of OJB can do the trick.

Subject: Experience in High-Load Environments
I realize I may be comparing Apples to Enterprise Applications here, but I'd like to hear some feedback about using OJB in high-load (load balanced?) environments.
On an OJB web application, how many requests have you seen an application handle? Would anyone be concerned about using OJB on an enormous e-commerce site? (EBay, Amazon, etc)?
Thanks for the input, Aaron
