Terminal Benchmarking Tools
Benchmarking is the practice of measuring how fast something runs under a repeatable workload, then comparing the numbers across versions, machines or competing implementations.
In the terminal that covers timing a command over many runs and reporting the spread, generating load against an HTTP server to find its requests per second, and measuring disk, memory and CPU throughput. Developers use the results to catch performance regressions before a release, and system administrators use them to size hardware.
Below is a list of terminal tools for benchmarking.
