This extension improving your website speed by working on different optimzations fields, one of the most powerful being the smart caching system which is saving some generated page (or parts of the page) for further display without having to re-process all the logic behind.
Failed to work from the start it crashed when turned off. Once corrected, my server had a problem with memory leakage, causing it to crash. Cpanel analysis showed the problem started the day the module was installed and stopped the day the module was turned off. Removing the module using installer crashed the site. The response was zero from developer.
It is very easy to use, powerful, and no monthly suscripción.
The developer is one of the best in opencart, very friendly and resolutive.
Totally recommended purchase!
I think this extension will be one of the most used in this platform, Congratulations.
