I have been trying to improve the site size and site speed of my site.
I have downloaded WP SMUSH and chosen all the appropriate settings to optimise my images. I have also download Autoptimise to help with JS and CSS. However despite this, Google Page Speed Insights and Pingback tests show a very slow performance and large size.
I am only a quarter way through building this soon-to-be online course and am concerned of how big and slow it may get in the future. The site is very heavily image orientated so WP Smush seems like a good solution. However through before and after speed tests, there is no difference. I cannot find any other reason why it would be so slow.
