Import csv on prestashop is too slow

I recently deleted the cache on prestashop, and after that I tried to import a file to change the category of 30k products, but it is too slow, it's been 8 hour and only changed the category of 190 products, so I need to solve that speed of the csv. I know this might be easy to solve so I offer just $10
