Subject: [gentoo-user] Speed up `du'

1 Is there any way to speed up the du command? I mean short of having
2 cron run it on target directories and store results. (not really
3 speeding up but at least not having to wait for a result)
4
5 I've seen various mention of du being slow but don't recall any
6 mentions of how to speed it up.
7
8 I use Reiserfs with default sizes. In some situations like a large
9 cache of nntp messages of several GB. I might wait 5-10 minutes or more
10 for du to get the size of the directory.
11
12 Are there other file systems that can return a result of `du' faster?
13
14 I'm curious how `df' computes sizes so much quicker. Even after
15 rm'ing a large amount of data... `df' sees the difference right away.
16
17 Or maybe there is some other tool or technique that can quickly tell
18 me the size of a directory or set of directories.
