## How to Benchmark my Code?
These guides teach you the fundamentals of benchmarking in your language, from
writing your first benchmark to running them continuously in CI.
}>
Learn benchmarking from scratch with pytest-codspeed: write benchmarks with
fixtures, parametrized tests, setup isolation, and integrate with CodSpeed
for continuous performance testing.
}>
Learn benchmarking from scratch with divan: write benchmarks with arguments,
type generics, dynamic inputs, and integrate with CodSpeed for continuous
performance testing.
}>
Learn benchmarking from scratch with google\_benchmark: write benchmarks with
arguments, fixtures, and integrate with CodSpeed for continuous performance
testing.
Learn benchmarking from scratch with JMH: project setup with Maven and
Gradle, parameterized benchmarks, JVM pitfalls, profilers, and CodSpeed CI
integration.
}>
Learn benchmarking from scratch with Go's standard library: sub-benchmarks,
parallel benchmarks, benchstat, pprof profiling, and CodSpeed CI
integration.
## Specialized Guides
Guides organized by topic, covering benchmarking strategies, API testing,
database performance, and framework-specific integrations.
### Benchmarking Strategy & Tools
}>
Compare different Python benchmarking approaches—from command-line tools
like `time` and `hyperfine` to integrated frameworks like `timeit` and
`pytest-codspeed`.
### API Performance Testing
}>
Build a Gin HTTP API, write clean benchmarks for all routes, optimize
measurement accuracy, and catch performance regressions in CI with
flamegraph analysis.
### Database Performance Testing
Advanced tutorials for benchmarking applications with database interactions,
including setup strategies and CI integration.
}>
Benchmark a NestJS API with MongoDB using Vitest benchmarks. Includes Docker and testcontainers setup patterns.
}>
Alternative approach using tinybench for MongoDB performance testing in Node.js applications.
