## Comparison to Other Tools
Startup time, lower is better.
| Tool | Time |
|----------------------------------------------------------|----------|
| [imghcprof](https://github.com/t4ccer/imghcprof) | 831 ms |
| [profiterole](https://github.com/ndmitchell/profiterole) | 7566 ms |
| [profiteur](http://github.com/jaspervdj/profiteur) | 7352 ms |
| [ghcprofview](https://github.com/portnov/ghcprofview-hs) | 31000 ms |
Note on methodology, time reported for `imghcprof`, `profiterole`, and `profiteur` is the mean from `hyperfine`. `ghcprofview` was measured by hand. `imghcprof` and `ghcprofview` were measured to first rendered GUI frame. `profiterole` and `profiteur` were measured to produce output file. `imghcprof` was instrumented to exit after first frame. All tools were tested on the same ~230MB prof file.
