I'd point at the following as being a sterling candidate for being a
cause of this being slow...
AND cont_publicacion.fecha_publicacion = (SELECT max(cp1.fecha_publicacion)
FROM cont_publicacion cp1
WHERE cp1.id_instalacion = cont_publicacion.id_instalacion
AND cp1.id_contenido = cont_publicacion.id_contenido
AND cp1.generar_vainilla = cont_publicacion.generar_vainilla)
May I suggest changing it to:
AND cont_publicacion.fecha_publicacion = (SELECT cp1.fecha_publicacion
FROM cont_publicacion cp1
WHERE cp1.id_instalacion = cont_publicacion.id_instalacion
AND cp1.id_contenido = cont_publicacion.id_contenido
AND cp1.generar_vainilla = cont_publicacion.generar_vainilla
ORDER BY fecha_publicacion LIMIT 1)
That would get rid of the aggregate that's sitting deep in the query.
