OpenSUSE Leap 42.1 vs. Leap 42.2 vs. Tumbleweed Benchmarks
Moving from Leap 42.1 to 42.2, the SQLite performance is much faster although still not as fast as Tumbleweed. OpenSUSE 42.1/2.2 ship with GCC 4.8 since that is what's used by SUSE Linux Enterprise for which the OS is in common. The Leap 42.2 faster SQLite performance is likely due to the newer kernel. The Clear Linux performance was the fastest since it ships with aggressive CFLAGS/CXXFLAGS set by default compared to most other Linux distributions.
The Parboil results show some more improvements for openSUSE Leap 42.2 over Leap 42.1 while in some cases Clear Linux and openSUSE Tumbleweed remain faster with their newer compiler and other differences.
In other tests, there isn't much of a difference.
