# benchmarks | |
This directory contains mojo applications that are run as performance benchmarks | |
by [mojo_benchmark](../mojo/devtools/common/mojo_benchmark). | |
See also: | |
- [documentation](../mojo/devtools/common/docs/mojo_benchmark.md) for | |
`mojo_benchmark` | |
## Legacy benchmarks | |
`benchmark_runner.py` and the `startup` benchmark are the remainings of the | |
previous take on performance benchmarks. These can be dropped once we can track | |
startup time of the shell itself using the new system. |
