The document discusses performance improvements of the Intel Xeon Processor 5600 series compared to previous generations. It summarizes that the 5600 series provides up to a 63% performance boost over the 5500 series. Benchmark results showed the Intel Xeon X5680 processor utilizing new AES-NI instructions provided a 10x speedup in AES encryption processing and 8x speedup in decryption compared to the Xeon X5560 without AES-NI. This allows Oracle Database 11g Transparent Data Encryption to run significantly faster on servers using Intel Xeon 5600 series processors.
