Oracle's Netra SPARC T4-2 Server equipped with two SPARC T4 processors running at 2.85 GHz set a world record result of 454.52 SPECjvm2008 Peak ops/m on the SPECjvm2008 benchmark. This result surpassed the previous record, which was run on a similar product, Oracle's SPARC T4-2 server. This level of performance is 41% better than the SPARC T3-2 server and similar in performance to Oracle's SPARC T4-2 server. The Netra SPARC T4-2 server with hardware cryptography acceleration greatly increases performance with subtests using AES and RSA encryption ciphers. There are no SPECjvm2008 results published by IBM on POWER7 based systems.

Among the important new features of the SPARC T4 microprocessor are several new instructions available to perform cryptography functions in hardware, according to a blog post from Dan Anderson. These instructions are used in the OpenSSL 1.0 t4 engine available in Solaris 11. These new crypto instructions are different from previous generations of SPARC hardware, which has separate crypto processing units. The major difference lies in solving the problem of kernel and buffer overhead, Anderson writes. These new instructions are non-privileged: any program can create or use these instructions—no kernel environment, root permissions, or special setup is needed, he explains.

The SPARC T4-2 Server equipped with two SPARC T4 processors running at 2.85 GigaHertz (GHz) and using Oracle Solaris 11 and Oracle JDK 7 Update 2 set a world record of 454.25 SPECjvm2008 Peak ops/m on the SPECjvm2008 benchmark, a benchmark suite for measuring the performance of a Java Runtime Environment (JRE). This level of performance is 41% better than the mark set by the SPARC T3-2 Server. The hardware cryptography acceleration built into the SPARC T4-2 was found to greatly increase performance on subtests using AES and RSA encryption ciphers.

Benchmark testing shows that the SPARC T3 processor running the IPsec AES-256-CCM can operate at near-line speed over a 10 Gigabit Ethernet (10 GbE) network, blogs Joerg Moellenkamp, who goes on to write that these results demonstrate more than 2x the throughput of the latest generation Intel Xeon processor. He adds that, with dedicated hardware support for encryption/decryption for AES and eleven other ciphers, the SPARC T3 processor is 12 times faster than the Intel Xeon processor for in-memory RSA decryption. Oracle's own announcement of these results asserts that, "This outstanding cryptographic throughput performance makes servers equipped with SPARC T3 processors an attractive platform for applications requiring secure network communications."
