Is there a better way to compare general performance of .Net and Java in an eCommerce setting than the "pet store"?

Question

I've been using the Java Pet Store and .Net Pet Store examples for years when comparing Java EE and .Net performance in an eBusiness type setting. Is there a better way to compare the performance of Java EE and .Net for this type of application?

Update:

As some have pointed out below, the implementation, framework versions, architecture, and hardware can have much more influence on performance than using .Net vs. Java. I wholeheartedly agree with this. However, keeping this in mind, I would still like to know what kind of general comparison would be best. Since the pet shop is a fairly mature and general eCommerce test case, I tend to think it's pretty useful for a baseline.

Answer 1

There is never really a definitive measure for comparing the performance of platforms. For example, a comparison of the same J2EE platform could be impacted by minor configuration changes. It would seem that the platform is less of a factor in performance today than it once was, whilst design and architecture will have a bigger impact.
