According to rh on 4/16/2008 12:14 PM:
| Hello,
| Running du -sk on an apache disk cache containing 10GB of data and
| 30,000 directories and files
| I see du using maybe .03% of the cpu. It takes an hour for it to complete.
Probably because du is I/O intensive; the cpu is probably rather idle
because most of your time is spent waiting on the disk to spin to the next
inode to inspect.
|
| Are there any plans to make du multi-threaded? Or otherwise improve
| it's performance? Is it filesystem sensitive? We are using ext3.
I doubt multi-threading will help an I/O bound process.
