I can't be doing this right ... |
| 32 |
|
| 33 |
I removed /var/lib/mlocate/mlocate.db, the ran updatebd: |
| 34 |
|
| 35 |
# time -p updatedb |
| 36 |
real 113.22 |
| 37 |
user 0.62 |
| 38 |
sys 8.00 |
| 39 |
|
| 40 |
Then removed it again and run it again: |
| 41 |
|
| 42 |
# time updatedb |
| 43 |
|
| 44 |
real 0m1.063s |
| 45 |
user 0m0.162s |
| 46 |
sys 0m0.896s |
| 47 |
|
| 48 |
Why is the second time so much faster? The size of the derived db was the |
| 49 |
same on both occasions. |
