# Running Benchmarks
This guide explains how to build and run performance benchmarks in the Nix codebase.
## Overview
Nix uses the [Google Benchmark](https://github.com/google/benchmark) framework for performance testing. Benchmarks help measure and track the performance of critical operations like derivation parsing.
## Building Benchmarks
Benchmarks are disabled by default and must be explicitly enabled during the build configuration. For accurate results, use a debug-optimized release build.
### Development Environment Setup
First, enter the development shell which includes the necessary dependencies:
```bash
nix develop .#native-ccacheStdenv
```
### Configure Build with Benchmarks
From the project root, configure the build with benchmarks enabled and optimization:
```bash
cd build
meson configure -Dbenchmarks=true -Dbuildtype=debugoptimized
```
The `debugoptimized` build type provides:
- Compiler optimizations for realistic performance measurements
- Debug symbols for profiling and analysis
- Balance between performance and debuggability
### Build the Benchmarks
Build the project including benchmarks:
```bash
ninja
```
This will create benchmark executables in the build directory. Currently available:
- `build/src/libstore-tests/nix-store-benchmarks` - Store-related performance benchmarks
Additional benchmark executables will be created as more benchmarks are added to the codebase.
## Running Benchmarks
### Basic Usage
Run benchmark executables directly. For example, to run store benchmarks:
```bash
./build/src/libstore-tests/nix-store-benchmarks
```
As more benchmark executables are added, run them similarly from their respective build directories.
### Filtering Benchmarks
Run specific benchmarks using regex patterns:
```bash
# Run only derivation parser benchmarks
./build/src/libstore-tests/nix-store-benchmarks --benchmark_filter="derivation.*"
# Run only benchmarks for hello.drv
./build/src/libstore-tests/nix-store-benchmarks --benchmark_filter=".*hello.*"
```
### Output Formats
Generate benchmark results in different formats:
```bash
# JSON output
./build/src/libstore-tests/nix-store-benchmarks --benchmark_format=json > results.json
# CSV output
./build/src/libstore-tests/nix-store-benchmarks --benchmark_format=csv > results.csv
```
### Advanced Options
```bash
# Run benchmarks multiple times for better statistics
./build/src/libstore-tests/nix-store-benchmarks --benchmark_repetitions=10
# Set minimum benchmark time (useful for micro-benchmarks)
./build/src/libstore-tests/nix-store-benchmarks --benchmark_min_time=2
# Compare against baseline
./build/src/libstore-tests/nix-store-benchmarks --benchmark_baseline=baseline.json
# Display time in custom units
./build/src/libstore-tests/nix-store-benchmarks --benchmark_time_unit=ms
```
## Writing New Benchmarks
To add new benchmarks:
1. Create a new `.cc` file in the appropriate `*-tests` directory
2. Include the benchmark header:
```cpp
#include <benchmark/benchmark.h>
```
3. Write benchmark functions:
```cpp
static void BM_YourBenchmark(benchmark::State & state)
{
// Setup code here
for (auto _ : state) {
// Code to benchmark
}
}
BENCHMARK(BM_YourBenchmark);
```
4. Add the file to the corresponding `meson.build`:
```meson
benchmarks_sources = files(
'your-benchmark.cc',
# existing benchmarks...
)
```
## Profiling with Benchmarks
For deeper performance analysis, combine benchmarks with profiling tools:
```bash
# Using Linux perf
perf record ./build/src/libstore-tests/nix-store-benchmarks
perf report
```
### Using Valgrind Callgrind
Valgrind's callgrind tool provides detailed profiling information that can be visualized with kcachegrind:
```bash
# Profile with callgrind
valgrind --tool=callgrind ./build/src/libstore-tests/nix-store-benchmarks
# Visualize the results with kcachegrind
kcachegrind callgrind.out.*
```
This provides:
- Function call graphs
- Instruction-level profiling
- Source code annotation
- Interactive visualization of performance bottlenecks
## Continuous Performance Testing
```bash
# Save baseline results
./build/src/libstore-tests/nix-store-benchmarks --benchmark_format=json > baseline.json
# Compare against baseline in CI
./build/src/libstore-tests/nix-store-benchmarks --benchmark_baseline=baseline.json
```
## Troubleshooting
### Benchmarks not building
Ensure benchmarks are enabled:
```bash
meson configure build | grep benchmarks
# Should show: benchmarks true
```
### Inconsistent results
- Ensure your system is not under heavy load
- Disable CPU frequency scaling for consistent results
- Run benchmarks multiple times with `--benchmark_repetitions`

# Release 2.31.0 (2025-08-21)
- `build-cores = 0` now auto-detects CPU cores [#13402](https://github.com/NixOS/nix/pull/13402)
When `build-cores` is set to `0`, Nix now automatically detects the number of available CPU cores and passes this value via `NIX_BUILD_CORES`, instead of passing `0` directly. This matches the behavior when `build-cores` is unset. This prevents the builder from having to detect the number of cores.
- Fix Git LFS SSH issues [#13337](https://github.com/NixOS/nix/issues/13337) [#13743](https://github.com/NixOS/nix/pull/13743)
Fixed some outstanding issues with Git LFS and SSH.
* Added support for `NIX_SSHOPTS`.
* Properly use the parsed port from URL.
* Better use of the response of `git-lfs-authenticate` to determine API endpoint when the API is not exposed on port 443.
- Add support for `user@address:port` syntax in store URIs [#7044](https://github.com/NixOS/nix/issues/7044) [#3425](https://github.com/NixOS/nix/pull/3425)
It's now possible to specify the port used for SSH stores directly in the store URL in accordance with [RFC3986](https://datatracker.ietf.org/doc/html/rfc3986). Previously the only way to specify custom ports was via `ssh_config` or the `NIX_SSHOPTS` environment variable, because Nix incorrectly passed the port number together with the host name to the SSH executable.
This change affects [store references](@docroot@/store/types/index.md#store-url-format) passed via the `--store` and similar flags in CLI as well as in the configuration for [remote builders](@docroot@/command-ref/conf-file.md#conf-builders). For example, the following store URIs now work:
- `ssh://127.0.0.1:2222`
- `ssh://[b573:6a48:e224:840b:6007:6275:f8f7:ebf3]:22`
- `ssh-ng://[b573:6a48:e224:840b:6007:6275:f8f7:ebf3]:22`
- Represent IPv6 RFC4007 ZoneId literals in conformance with RFC6874 [#13445](https://github.com/NixOS/nix/pull/13445)
Prior versions of Nix since [#4646](https://github.com/NixOS/nix/pull/4646) accepted [IPv6 scoped addresses](https://datatracker.ietf.org/doc/html/rfc4007) in URIs like [store references](@docroot@/store/types/index.md#store-url-format) in the textual representation with a literal percent character: `[fe80::1%18]`. This was ambiguous, because the the percent literal `%` is reserved by [RFC3986](https://datatracker.ietf.org/doc/html/rfc3986), since it's used to indicate percent encoding. Nix now requires that the percent `%` symbol is percent-encoded as `%25`. This implements [RFC6874](https://datatracker.ietf.org/doc/html/rfc6874), which defines the representation of zone identifiers in URIs. The example from above now has to be specified as `[fe80::1%2518]`.
- Use WAL mode for SQLite cache databases [#13800](https://github.com/NixOS/nix/pull/13800)
Previously, Nix used SQLite's "truncate" mode for caches. However, this could cause a Nix process to block if another process was updating the cache. This was a problem for the flake evaluation cache in particular, since it uses long-running transactions. Thus, concurrent Nix commands operating on the same flake could be blocked for an unbounded amount of time. WAL mode avoids this problem.
This change required updating the versions of the SQLite caches. For instance, `eval-cache-v5.sqlite` is now `eval-cache-v6.sqlite`.
- Enable parallel marking in bdwgc [#13708](https://github.com/NixOS/nix/pull/13708)
Previously marking was done by only one thread, which takes a long time if the heap gets big. Enabling parallel marking speeds up evaluation a lot, for example (on a Ryzen 9 5900X 12-Core):
* `nix search nixpkgs` from 24.3s to 18.9s.
* Evaluating the `NixOS/nix/2.21.2` flake regression test from 86.1s to 71.2s.
- New command `nix flake prefetch-inputs` [#13565](https://github.com/NixOS/nix/pull/13565)
This command fetches all inputs of a flake in parallel. This can be a lot faster than the serialized on-demand fetching during regular flake evaluation. The downside is that it may fetch inputs that aren't normally used.
- Add `warn-short-path-literals` setting [#13489](https://github.com/NixOS/nix/pull/13489)
This setting, when enabled, causes Nix to emit warnings when encountering relative path literals that don't start with `.` or `/`, for instance suggesting that `foo/bar` should be rewritten to `./foo/bar`.
- When updating a lock, respect the input's lock file [#13437](https://github.com/NixOS/nix/pull/13437)
For example, if a flake has a lock for `a` and `a/b`, and we change the flakeref for `a`, previously Nix would fetch the latest version of `b` rather than using the lock for `b` from `a`.
- Implement support for Git hashing with SHA-256 [#13543](https://github.com/NixOS/nix/pull/13543)
The experimental support for [Git-hashing](@docroot@/development/experimental-features.md#xp-feature-git-hashing) store objects now also includes support for SHA-256, not just SHA-1, in line with upstream Git.

## Store Derivation {#store-derivation}
A derivation is a specification for running an executable on precisely defined input to produce on more [store objects][store object].
A derivation is a specification for running an executable on precisely defined input to produce one or more [store objects][store object].
These store objects are known as the derivation's *outputs*.
Derivations are *built*, in which case the process is spawned according to the spec, and when it exits, required to leave behind files which will (after post-processing) become the outputs of the derivation.

We can take the [transitive closure] of the references graph, in which any pair of store objects have an edge if a *path* of one or more references exists from the first to the second object.
