I just purchased your theme and went on to check google page speed insight and this is scary:-

1). developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fmagento2.magentech.com%2Fthemes%2Fsm_revo%2F

2). gtmetrix.com/reports/magento2.magentech.com/RI2RK9px

Result is not only scary but “suicidal”.

a). approx 1mb of js requires to be minified

b). 200+ request on each load. Users are going to run away from site even before thinking to purchase and product.

Dear iFreelance Asia,

Thanks for contacting Magentech!
Our theme is included many modules so there were a lot of queries need loaded.
The loading time is also the problem of magento 2 sites in general.
You can follow this post below to improve the site performance:
