Bugzilla sizes

I recently did a talk "The Evolution of Bugzilla" at the Oxford 
University Computing Society. It talked about how the software changes 
and developing under pressure, not how it came into being ;-P

As part of that, I generated some interesting information which I will 
share with you. There are some stats, and a mockup of what a Bugzilla 
bug looked like back in 1998.

Stats
=====

Mozilla: 420,000 bugs, 39 products, 627 components
Gnome:   398,000 bugs, 447 products, 1469 components
Red Hat: 191,000 bugs, 59 products, 7580 components (loaded via Ajax on
                                                   the standard bug page)
KDE:     160,000 bugs, 395 products, 930 components
OpenOffice.org: 86,000 bugs

b.m.o. has 301,000 user accounts, of which 3,400 were active in 2008, 
and 15,000 in 2007, and 305,000 attachments. The database size is 9.3GB, 
of which 6.6GB is attachments. The slide set has details of current 
hardware.

Of course, the largest known Bugzilla is none of these; Yahoo's had 1.6 
million bugs in December last year.

Mockup
======

By doing replacing by hand in the code (as it won't run with my current 
Perl and MySQL), I mocked up what a bug looked like in Bugzilla 2.0, the 
first Perl release.

Minimalist, huh? :-)
