Performance cost of Java dynamic proxy

Question

Many modern frameworks (Spring, Hibernate) provide very nice dynamic behaviors with use of Java dynamic proxies, but what's the exact performance cost associated with it? Are there public benchmarks available for Sun JVM?

Answer 1

A few pointers:

• Debunking myths: proxies impact performance (have a look at the comments too)
• Java theory and practice: Decorating with dynamic proxies
• Benchmarking the cost of dynamic proxies
