Yes right.
Valentina for Cocoa will have price $199 by the way.
But when developer get show stopper problems, Valentina can help.
I also have made fast benches of SQlLite 3.
On db with 100MB (million records in one table), SqlLite did response on
different SIMPLE queries up to 30 seconds. More complex queries such as
select distinct * from T
take minutes. I did wait 7 minutes and interrupt.
Valentina all queries answer on this db in about 0.1 seconds.
Again, I even did not test more complex things, as joins, group by, distinct
on join, and so on... If single table query is so slow all rest is out of my
interest.
