Upon the release of the first Mac OS X 10.7 “Lion” Developer Preview, we had delivered early benchmarks of this Apple operating system slated for release this summer. Since then, there has been the release of Mac OS X 10.7 Developer Preview 2 (DP2) so we have carried out an updated set of Mac OS X 10.7 performance benchmarks. This also includes a comparative look at the Mac OS X Lion performance against Ubuntu Linux 10.10.

This testing compares the performance of Mac OS X 10.6.6, Mac OS X 10.7 Developer Preview 1 (Build 11A390), Mac OS X 10.7 Developer Preview 2 (Build 11A419), and lastly for reference were Ubuntu 10.10 x86_64 benchmarks. With Mac OS X 10.7 11A419 it’s reporting an 11.0.0 64-bit kernel, X.Org Server 1.9.5, NVIDIA graphics, case-sensitive Journaled HFS+ file-system, and we were using the latest Xcode3 package providing GCC 4.2.1 and LLVM/Clang 1.6.

With Ubuntu 10.10 x86_64 we were using a stock package set of the Linux 2.6.35-22-generic kernel, X.Org Server 1.9.0, NVIDIA 260.19.06 binary driver, an EXT4 file-system, and we had manually installed GCC 4.2.1 to be comparable to Apple’s Xcode release used on Mac OS X 10.7 builds and Mac OS X 10.6.6.
