Now, an easy way of getting the same result, with a little bit more of work but achieving the best performance, is just using an opaque pointer in the GObject’s public structure and define, allocate and deallocate it yourself in the source file (so also can be treated as private, as the users of the API don’t know the internals of the structure).
These are the basic changes you need to do to avoid calling G_TYPE_INSTANCE_GET_PRIVATE():
**** In the HEADER of the GObject, when the struct defining the Object is specified, add a “gpointer priv” variable.
struct _MyGObject
{
    /** Parent object */
    GObject parent;
    /** Private data pointer */
    gpointer priv;
}


**** Then, in the SOURCE of the GObject, modify the GET_PRIVATE macro so that instead of doing the standard GObject lookup for the correct type, we just get the opaque “priv” pointer defined in the header, and we cast it to the correct type.
#define MY_GOBJECT_GET_PRIVATE(o) \
    ((MyGObjectPrivate *)((MY_GOBJECT(o))->priv))


**** As we won’t use the automatic allocation of the Private data structure, we need to allocate it ourselves in the _init() function.
static void
my_gobject_init(MyGObject *self)
{
    /* Allocate Private data structure */
    (MY_GOBJECT(self))->priv = \
        (MyGObjectPrivate *) g_malloc0(sizeof(MyGObjectPrivate));
    /* If correctly allocated, initialize parameters */
    if((MY_GOBJECT(self))->priv != NULL)
    {
        MyGObjectPrivate *priv = MY_GOBJECT_GET_PRIVATE(self);
        /* Initialize private data, if any */
    }
}


**** And finally, the last change is just de-allocating the structure when no more needed in the _dispose() function.
static void
my_gobject_dispose(GObject *object)
{
    MyGObject *self = (MyGObject *)object;
    MyGObjectPrivate *priv = MY_GOBJECT_GET_PRIVATE(self);
    /* Check if not NULL! To avoid calling dispose multiple times */
    if(priv != NULL)
    {
        /* Deallocate contents of the private data, if any */
        /* Deallocate private data structure */
        g_free(priv);
        /* And finally set the opaque pointer back to NULL, so that
         *  we don't deallocate it twice. */
        (MY_GOBJECT(self))->priv = NULL;
    }
}
