Any important reason is that every online buyer prefers sites that their pages load very fast within a second. 

Only consider getting hosting from a better hosting provider and make sure you use a lightweight framework/theme. As you are reducing your image sizes, don't forget to minimize your CSS and JS files too. 

In addition, make use of advanced caching mechanisms with a caching plugin and don’t hesitate to use CDN (Content Delivery Networks). Lastly, clean up your WordPress database, deactivate unwanted plugins, have minimalistic external scripts and enable GZIP compression.
