Recently I am facing high loading speed in my Magento store. I have also made the priority js code for content in the web page. so Refrain JS from loading upfront. and also I have compressed many files including CSS minification, gzip compression etc. all my images are well optimized since then my website load speed is high. I have also come across from one of consultant ecommerce agency in usa
regarding my issue, they asked for migration to Magento 2 . is it possible to reduce load time with Magento 1 or I need to migrate to Magento 2?
