carga en pagina de producto lenta

[comercial2]

hola!

Tengo prestashop 1.7.8.7 y desde hace unos días he notado que me carga muuuy lenta la pagina de la ficha de producto, pero el listado y la home me cargan normal. he ido borrando zonas de la pagina para ver cual es la que hace que cargue más lento y es el product-prices.tpl. Si dejo este archivo en blanco, la pagina carga 10 segundos más rápido. El codigo es el siguiente, no consigo saber qué puede haber cambiado para que vaya tan lento.
