In the wake of the SPARC T5/M5 launch last week, there's a lot we can discuss, especially related to performance.
To start with: we've just released an update to Oracle Solaris Studio, with compiler optimizations specifically designed to get the most performance out of applications on Oracle T5, Oracle M5, and Fujitsu M10 systems.
Oracle Solaris Studio compilers generate code that is up to five times faster than code compiled with open source alternatives, and this Platform Specific Enhancment (PSE) to Oracle Solaris Studio 12.3 can get you up to 10% more performance on the latest SPARC processors than code generated with the pre-update 12.3 release.
