Performance, Agility, and Cost Savings: IBM SDK5 and SDK6 on System z

The adoption of Java on mainframes continues to grow. As such, IBM has invested heavily in its SDK technology on System z. With SDK5 and SDK6, the IBM JVM was re-engineered, providing a significant improvement in performance, security, reliability, and serviceability. As a testament to the value of IBM's investment, this paper demonstrates incremental performance and scalability improvements with each level of the SDK. When combining these improvements with the cost effectiveness of IBM Specialty Engine zAAPs and thread speedup of new processors such as the z10, the ever-growing value proposition of Java on System z is undeniable.
