As the latest Phoronix benchmarks to deliver, after I finished that VMware Fusion 6.0.0 testing on Ubuntu 13.04 from the Haswell-based MacBook Air system, I upgraded to Ubuntu 13.10 to see if there's any performance improvements to find with the 13.10 "Saucy Salamander" packages over 13.04 stable.
Long story short, there wasn't too much to get excited about. While there's an updated kernel several releases ahead, the Mesa 9.2 graphics stack, GCC 4.8, etc, it didn't translate to much of a difference in the VMware Fusion guest.
The 13.04 vs. 13.10 x86_64 benchmarks from the Haswell MacBook Air via VMware Fusion 6 can be found on OpenBenchmarking.org within 1309195-SO-SAUCYVM1385. Embedded below are just a couple of the results.
For most of the tested workloads, there was only a minor difference in the upgraded Ubuntu Linux state.
