ab (ApacheBench)
ab (ApacheBench) — Apache HTTP server benchmarking tool for measuring requests per second and latency from the command line.
Our Verdict
A quick-and-dirty benchmark hammer that is great for one-off checks but wrong for serious load testing.
Pros
- Ships with Apache, zero install on most Linux boxes
- Dead simple CLI for quick RPS and latency checks
- Negligible resource footprint on the load generator
- Perfect for smoke-testing a single endpoint fast
Cons
- Single-threaded, struggles to saturate modern servers
- No scripting, cannot chain requests or vary payloads
- HTTP/1.0 only, no keep-alive reuse across connections
- Coordinated omission skews latency percentiles
When to Use ab (ApacheBench)
Good fit if you need
- Benchmark REST endpoints at 10K requests/sec
- Measure latency percentiles before and after optimizations
- Stress test Apache/Nginx configs with concurrent connections
- Quick smoke test after deployment to verify throughput
