Er. Well. Sorry about that, here are corrected figures: |
| 7 |
54 seconds -> 16 seconds == 3.3x improvement. |
| 8 |
Therefore: |
| 9 |
17 configure scripts (before splitting ebuilds) --> 20-60 minutes total |
| 10 |
running time |
| 11 |
splitting up --> >=220 packages (? but at least that many, I believe) |
| 12 |
splitting up without confcache --> 220-660 minutes, i.e. 3.6-11 hours, total |
| 13 |
running time (clearly unacceptable) |
| 14 |
splitting up with confcache --> about 25-30% of above, i.e. 1-3.3 hours total |
| 15 |
running time |
| 16 |
|
| 17 |
According to these numbers, if we both add confcache and split the ebuilds, |
| 18 |
the total time for emerging all or nearly all of kde will increase by 0.6-2.3 |
| 19 |
hours. |
