ps release 1.6.1.11 had 'significant' update to solve poor bo performance similar to what you described.

 

there must be reason you upgrade only to 1.6.1.10 but I suggest you upgrade to .11 or higher to see if resolves this issue.

Now I have upgrade PS from 1.6.1.10 to 1.6.1.14 
upgrade also php from 5.5.38 to 5.6.30

But the site go slow slow

for example here : https://www.oriente-import.it/en/35-trousers-cotton-and-elastane


But the staff of A2 hosting write me this:
"
Unfortunately, I think the culprit here lies within your PrestaShop configuration along with the pretty voluminous database that it's using. I have tried various of methods to apply some of the latest server features, like upgraded PHP environment, Lite-Speed tweaks in addition to speed up the script execution, upgrade to your MySQL server, but the website didn't provide any indications of improving the overall performance. 

Mine advice here will be to contact an expert in PrestaShop development and request an overall investigation of your website performance, which could further provide you with any pieces of evidence of what could be improved here.
