Those ext3 on a local drive? And is it sqlite2 or sqlite3?
Seems like I do 6K in about 90 sec (?), so that makes you slow by a about a half. What kind of files are they?
Filesystem is ReiserFS, lvm on md (may only be bad on writes, not reads)
most files (99%) are .mp3
db backend is sqlite3, gentoo has no support for sqlite2 afaik
