# Running times for 6_report as a function of area

Tool: Global Routing

Subcategory: Performance issue

## Conversation

Using https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/pull/1211 and executing `python util/plot-running-times.py`, I've plotted some running times against area:



`6_report` running time in seconds below. Note that the x axis is um^2, but that it is multiplied by 1e6 (as can be seen in the lower right corner).

As can be seen, the running time is worse than proportional to area and I imagine that there could be some low hanging fruit as I would expect reporting not to be on the order of detailed routing times.

```

cat /proc/cpuinfo | grep processor | wc -l 

12

```

Same for `2_6_pdn`, here running time is proportional to area:

`5_2_TritonRoute` running times are misleading as there's some sort of problem with DRC errors #3592

However, since I have the data, I include the plot here anyway.

A feature request has been filed to improve reporting times #3599
