232,211 users; 102,644 attachments. Active stuff I'll check later.

Our bug rate will go down in future due to crash.gnome.org; loads of
stuff goes still directly to Bugzilla. In future it will mostly use
crash.gnome.org. ATM I think it is ~1,500/week. It used to be ~500 some
years ago. However, it went down drom 2,500/week (most of 2007).

Database is 6.4GB:
 1.2GB are indexes (*.MYI).
 2.8GB attachment data (excluding indexes)
 2.1GB comments data (excluding indexes)

comment indexes are 938MB btw... possibly splitting longdescs like
attachments (not on bgo.. too old Bz) would provide a speedup.
