Hello,
Thanks for your Patience!
While we are committed to provide you with Quality Support, we unfortunately, cannot control your Hosting Environment or Server Configurations. When we received your Support Query, these are the Steps we followed:
Checked your Website on Pingdom Tools to analyze your Website's Speed.
Checked your Website on Google Page Speed to check the Optimization Suggestions.
Checked your Website on W3C Validator for HTML Validation errors.
Checked the Codes on Developer Console for Possible Errors.
And after that we came to the conclusion that it was your Hosting Servers and Configurations that are causing these issues as it did not appear optimized which is why we had provided you with the suggestion to go through the Optimization Tips provided as they would help you load your website faster. Now, Canvas is a Static Template and nothing is dynamic, so there is no reason for the Websites running on Canvas codes to be slow except for the fact that the File Sizes are larger than expected which can be Images or Videos or the CSS/JS Files. For the Images and Videos, it is your responsibility to optimize them and use optimally sized assets. For the included CSS/JS Files, since Canvas is a Multi-Purpose Template, everything is included by default and it is the user's responsibility to include/exclude the codes according to what is required for their website. We provide tools like Custom JS Package Generator: http://support.semicolonweb.com/js-package-generator/ and for CSS, you can consider using the css/imports Folder and the style-import.css File to include/exclude the CSS according to your usage requirements. The CSS Files in css/imports Folder are the mirror copies of the style.css but broken into parts so that you can simply use the CSS Styles you actually need for your Website. Start with the style-import.css File and remove the @import references for the Elements Styles you do not need for your Website.
Support is provided only for the issues or bugs arising from the Design and Functionality Features already included with Canvas and not for User Customizations as this could be limitless. Speed Optimizations are based on User's Content, Hosting Environment, Server Configurations or CDN Usage and falls under Customization. And unfortunately we currently do not provide Customization related Support according to the Item Support Policy: https://themeforest.net/page/item_support_policy . You will need to optimize your Website manually. For any other issues covered within the Support Policy, we are always here to help you.
Hope this Helps!
