+## Benchmarks
+
+For the benchmarks I am using Windows 7 64bit on my Laptop which has the following Hardware:
+- Intel i7-3632QM, 16GB RAM, Samsung 1TB SSD (EVO 850), disabled swap space
+- the compression benchmarks are written to SSD, the decompression benchmark is in RAM via: `7z t archiv.7z`
+- the tool for measuring the times is [wtime](https://github.com/mcmilk/wtime), together with some [scripts](https://github.com/mcmilk/7-Zip-Benchmarking)
