- **Parallel execution** shows how much of the build execution time was spent running steps in parallel.
The chart colors and legend keys describe the different build operations. Build
operations are defined as follows:
| Build operation | Description |
| :------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| Local file transfers | Time spent transferring local files from the client to the builder. |
| File operations | Any operations that involve creating and copying files in the build. For example, the `COPY`, `WORKDIR`, `ADD` instructions in a Dockerfile frontend all incur file operations. |
| Image pulls | Time spent pulling images. |
| Executions | Container executions, for example commands defined as `RUN` instructions in a Dockerfile frontend. |
| HTTP | Remote artifact downloads using `ADD`. |
| Git | Same as **HTTP** but for Git URLs. |
| Result exports | Time spent exporting the build results. |
| SBOM | Time spent generating the [SBOM attestation](/manuals/build/metadata/attestations/sbom.md). |
| Idle | Idle time for build workers, which can happen if you have configured a [max parallelism limit](/manuals/build/buildkit/configure.md#max-parallelism). |
### Build dependencies
The **Dependencies** section shows images and remote resources used during
the build. Resources listed here include:
- Container images used during the build
- Git repositories included using the `ADD` Dockerfile instruction
- Remote HTTPS resources included using the `ADD` Dockerfile instruction
### Arguments, secrets, and other parameters
The **Configuration** section of the Info tab shows parameters passed to the build:
- Build arguments, including the resolved value
- Secrets, including their IDs (but not their values)
- SSH sockets
- Labels
- [Additional contexts](/reference/cli/docker/buildx/build/#build-context)
### Outputs and artifacts
The **Build results** section shows a summary of the generated build artifacts,
including image manifest details, attestations, and build traces.
Attestations are metadata records attached to a container image.
