Peter Kovgan commented on DERBY-465:
------------------------------------

Multithreading test I did compromises Derby(at least I think so , but I may 
change my opinion...) and I need your suggestions how to  improve this 
situation.
Thank you.

> I have tested 4 major embedded DB.
> I have found that major disadvantage of Derby is 
> 1)low insert speed and 
> 2)significant performance degradation in select, update, delete  operation 
> speed starting from some table size.
> PointBase in comparison has not such degradation.
> It will be better if you improve your product.
> Good luck and thank you.
