http://www.gnome.org/~davyd/gnome-2-14/ has more details on the
optimisations.  I found the first chart pretty amusing, though 
I'm sure I don't know the whole story:

   GMemChunk:  26s
   Malloc:      4s
   GSlice:      2s

So, on first glance that's a massive win -- the allocator's been made
thirteen times faster!  On the other hand, it raises the question of
why they wrote *and then used* an allocator without noticing that was
over six times slower than *malloc*.  :)

At least on Ubuntu, the version of OO installed on the 64-bit
distribution is the 32-bit binary using 32-bit compatibility
libraries, so it makes sense that it might be sluggish compared
to native 32-bit.
