AWS m7i & m7i-flex Performance/Price - sysbench RAM

Go back to list

sysbench RAM is micro-benchmark part of the sysbench command line. Its goal is to stress volatile memory in write or read access and report performance as MB/sec

Our goal is not to reach the maximum bandwidth, so our configuration uses the default 1KB block, a number of thread equal to the CPU and read then write access. Below, you'll find an example of configuration

sysbench --threads=$cpu_number --time=60 memory --memory-oper=$access run
