About Grid.

Sergey have made for Vtable datasource to be used easy with binding.
Our API_way examples use that.

And as I know, Cocoa Grid do correct job like Einhugur's DataGrid.
I.e. It implement kind of ACTIVE Grid, which self ask app only for required
rows/cells to be displayed right now.

I do not expect any overhead here.

My expectation is that Cocoa grid will scroll table with million records
with the same easy and speed as do Einhugur's DataGrid.  But we have not try
todo this yet.


------
If you have see slow issue in CocoaMySQL then let me ask:

    you mean that you have try to browse table with a lots of records?

I think this not works good for mySQL, because they use only client-side
cursors. You need load only few records to client RAM.

Isale...CoreData   :-)   nope, 3 times :-) :-) :-)
  
CoreData is based on SQLLite. So why you want to see here high performance?

WE all here know that SQL Lite is much slower of Valentina
Even if REAL and Apple will prove to the whole world that it is not true.


Dave, have you see on our testimonials page quote from Justin Druri?
Read it if you have not yet.
