The catalog is of course a hotspot. There is collective.indexing and the 
catalog queue that ease the pain a bit and bring some improvements to 
the overall performance (for both Plone and CMF) - however not as
satisfying as I was thinking of. Going with a RDBMS as backend is likely 
the only option when it comes scalablity on a system with lots of 
concurrent write.
