This will be also comparsion between rdbms and oodbms. So, does not say much 
about oodbms.

For my sake, I've tested it on simple 'discussion table' (i. e. name, e-mail, 
text) with generating random values.

Size was around 4 GB, it took a few hours to generate. 

Then, when selecting "select * from tbl where id=x" and corresponding action 
in zodb, zodb was about 10x slower. However, that was not tested with 
IndexedCatalog. (tested with Firebird)

However, use zodb when you need oodbms. I'm personally overusing it because I 
don't have to "dirty" my code with or mapping. However, strength of oodbms is 
when dealing with object data (that means lot of joins and complicated 
mapping with rdbms).
