TTFB issue when Prestashop Cache module is enabled

Hi!

I have installed the Litespeed Prestashop module and the results are an atrocious 3 to 20 seconds waiting time for TTFB (!!!) when the module is activated. If I disable the module and use the 'native' Litespeed cache, I get a perfect TTFB of 210 ms...

Now I could use the native cache mode, but from the wiki, it appears that further configuration with rewrite rules are needed. Why is the module causing such terrible wait times??????

Litespeed Prestashop module should not cause long TTFB. it could be something else and may need further investigate. Can you enable prestashop cache plugin back and provide your test URL?
