The integration of JIT compilers, more sophisticated garbage collectors, and improvements in the JVM runtime environment have allowed many Java applications to meet their performance requirements. Even with the many enhancements added to modern JVMs, performance and scalability remain important to application stakeholders. For example, many applications have increased their performance requirements and performance service level agreements. Additionally, new families or classes ...
