I've just upgraded my program from using v2.8.16 of sqlite to using v3.2.1 of sqlite. So I've change the wrapper class that I was using to use the new prepare() instead of compile() etc. The problem I have is that my program is now running slower - a lot slower, as in one fiftieth of its previous speed. Is there something obvious that I have overlooked in the changes ? I've added indexes to tables and synchronous is now off but its made no improvement.
