vhr-bench
Benchmark a Linux server's CPU, memory and disk IOPS in about a minute
vhr-bench is a single MIT-licensed Bash script that benchmarks a Linux server in about a minute: sysbench CPU and memory, plus fio 4k random read and write IOPS. It asks before installing sysbench or fio, sends nothing anywhere unless you pass an upload token, and --cleanup removes the packages it installed. I use it to check a new VPS before deploying to it, and to compare hosts and plans on equal terms.
Run it once:
curl -fsSL https://github.com/vpshostreview/vhr-vps-benchmark/releases/latest/download/vhr-bench | bash -s -- --cleanup
