[Flops](https://github.com/Mysticial/Flops is a nice tool for benchmarking floating point operations of a CPU.
Under Arch Linux i had some problems compiling it, because the static linking towards openmp was not working properly. I’ve made a pull request and hope, it will be included in the mainline soon.
The tool itself is quite nice to compare the throughput of FLOPS on a CPU. It measures it under lab conditions so be aware that the everyday performance will be lower.
Nice tool :-)
