I'm sure they do on some occasion if they encode compressed audio/video, |
| 10 |
or when compressing data with zip/etc. That is probably the biggest |
| 11 |
application of cpu-bound software. |

Personally, I use -Os across the board when it doesn't break. As you |
| 14 |
said I tend to be memory/IO bound, and optimizing for size helps with |
| 15 |
both (swapping causes IO). I'd probably benefit from using -O3 on the |
| 16 |
aforementioned CPU-intensive apps. |
