Measuring approximate CPU speeds with openssl

I use a variety of hardware in my day-to-day activities, and was curious to see how they compared to each other. While I could run a micro benchmarking tool to get detailed information on memory, cpu, network and disk throughput, I thought it would be easier to use openssl’s ‘speed’ option to get a rough approximation of each machines capabilities. The results are listed below:
