I'm just curious on why fetching cached data is so slow. But now, I'm 
not sure
my approach is correct or not. I'm not expert on using EOF, which 
means I could
make a big mistake on using EOF.

Attached file contains programs which I use for checking speed. :-) 
It's very ugly testing
program, but anyway, I'm in process of learning EOF :-) Fastest one is 
main-deof, which
uses EOF, but fetched data is cached using NSDictionary.

Thanks in advance.
