Yes, absolutely.

We not talking about "plain" read data in RB, but about using my ORM  
framework. Perhaps it could *NOW* been optimized, because some RB  
features are now available, that was not, when I designed my framework.

So issue with RB is, that everything needed or perhaps better I want  
to have at my hands like key-value-coding must be implemented by  
myself with really complicated code. A lot of "list" and context  
handling, too - everything delivered by Cocoa for  "free".

So the bottleneck here is NOT RB as RB, but an ORM concept in RB.


But on the other hand the build apps was really usable, sometimes a  
little bit slow, but still usable. So the customers who are going  
migrate will blown away from their screens when doing the first big  
search :-)

thanks :-)
