# Performance Profiler

{% hint style="info" %}

{% endhint %}

For Grasshopper script designers, it is important to know what components take longer time and where is the bottleneck. Pancake provides a tool of profiling a part of your script with higher accuracy and error control.

### How to use this feature?

* Select one or more components,
* Left-click an empty place on the canvas while holding Ctrl and Shift
* Click **Profile selected components (new run)**
* Wait for a while. The process can take at least 5 seconds and up to 10 times the duration of a single run.

### How to interpret the report?

A typical report reads like (some lines are omitted):

```
