The rpmdb is a bunch of db4 files. In don't think I want to interfere with
the db4 engine...
They're often badly fragmented, too :) But whether or not that matters
much for rpm performance, I dunno.
[root@host ~]# filefrag /var/lib/rpm/Packages
/var/lib/rpm/Packages: 844 extents found, perfection would be 1 extent
[root@host ~]# ls -lh /var/lib/rpm/Packages
-rw-r--r-- 1 rpm rpm 52M Apr 27 15:40 /var/lib/rpm/Packages
Somehow XFS is doing a much better job. This is from a four year old system:
$ sudo filefrag /var/lib/rpm/Packages
/var/lib/rpm/Packages: 2 extents found
$ ls -lh /var/lib/rpm/Packages
-rw-r--r-- 1 rpm rpm 88M 2009-04-28 10:18 /var/lib/rpm/Packages
