Tried it with C++ Builder & third party VCL from IBDAC.
The speed is about the same with flamerobin, load in sec.
Records in flamerobin's status bar shows 11922.
So, it seem that TSQLQuery, for now is rather slow.
Well, at least, there is a room for improvement.
I will try Lazarus 2, but not in near time. One on my app in Lazarus use a package, and not sure if this package will runs OK in ver 2.
