cache PrestaShop 1.6.1.12 combined cache options

[Black RL]

Hi,

 

I've searched a lot but I didn't find a definitive answer, I don't know if I should activate the last cache option of PrestaShop or not, the one under advanced>performance, some people say that if OpCache is enabled then it should't be activated, others say the more the better, this is what I have:

 

SERVER

OpCache on

Full compression including GZip on

 

PRESTASHOP

Smarty with cach on

.........

Cache off
 

Should I activate it? And if yes can you please help me choose the best option? Memcached? Thanks.
