sysbench is an open source multi-threaded performance testing tool, performance testing can be performed on the CPU / memory / thread / IO / databases. It can apt install sysbenchbe installed.
When the CPU test, calculates prime number (divided by total number between 2 and the square root of this number to this number to verify the prime) time until a specified desired value.

DDR Performance Test
Created on the small machine memory disk, cache frequently read and write and have the required speed small files into memory, of course, it can also be used to test the read and write speed:
