This is just the most recent ARM Linux benchmarks on Phoronix. For the week already have been:
Benchmarking Ubuntu Linux On The Google Nexus 10 - This is the big article looking at the performance of the Google Nexus 10 (Samsung Exynos 5 Dual; ARM Cortex-A15 SoC) running Ubuntu Touch compared to numerous other x86 and ARM devices. Benchmarking of the Google Nexus 7 from Ubuntu Touch is forthcoming.
Plus other ARM Linux articles. In the coming days will be the talked about Google Nexus 7 results from running Ubuntu Touch, plus numerous other Linux benchmarks still being planned. At the moment it's still undecided whether to benchmark the Google Nexus 4 with its Qualcomm "Krait" Snapdragon S4 Pro SoC, if you're interested in those numbers, read this information. You can also see the Phoronix February stats for all the work that's involved.
Anyhow, the ARM GCC LTO benchmarks for your Saturday viewing can be found in full on OpenBenchmarking.org within 1303016-PTS-GCC48ARM14. Embedded below are the highlights from this benchmarking from the NVIDIA Tegra 3 Cardhu tablet.
There are some performance improvements to see out of GCC Link-Time Optimizations from GCC 4.7.2. This feature is enabled via the "-flto" compiler switch that can be set via the CFLAGS/CXXFLAGS.
The compile time obviously increases when applying link-time optimizations.
