Hello,
I wanted to run some Programs inside Qemu on Hosts that don't support Virtualisation for several reasons (like transparent High-Avability). So I wondered, which Guest Architecture is the Fastest in Qemu? Here are some benchmarks using qemu-user:
First is nbech, which tells us the Relative Performance to an Pentium 90 or AMD K6/233 (MEM/New*). As it is static, it mainly tests the JIT Performance of Qemu's TCG.
You may wonder, why there are less Architectures on the Arm hf Host, well that's Because qemu-user isn't Perfect and those Benchmarks simply Crashed there (Segfaults, etc.).
Here the Same Charts, but sorted by FP-Performance:
And last, but not least Interpreter Performance, using Scimark on lua/luajit, which tells us Mflops:
BTW: Luajit on Qemu was always faster than native Lua.
These are just first Measurements, I think I'll take the 5 best from both Hosts and Benchmark them using full System Emulation.
