Benchmarks: data ccompression and encryption

We run five data compression and encryption benchmarks. First we compress 2GB of data using both 7Zip as well as Winrar. We also run three parts of the AIDA64 benchmark. Zlib is a popular compression method that is used by a lot of software. AES is one of the most used encryption algorithms and is, for example, the basis for the SSL-encryption of HTTPS-websites. With AIDA64 we also measure how fast data can be hashed.

The i7 2600K is still quite good in 7-Zip, where it is almost as fast as the Ryzen 5 1600. The 2500K is just a bit faster than the Pentium. In Winrar we see approximately the same results. The encryption tests are clearly easier on new processors, which often have specific optimisations for this purpose.
