index-onepage.html Loading times - How to shorten the loading time?

Hello Semicolonweb team,
Thank you for the nice, feature rich HTML5 templates. I've started building a rather large website months ago and completed about 90% of the website.
But today, when I tested the website on the web server, I've noticed that it takes more than 10 seconds to load the whole index-onepage.html file that I created which contains lots and lots of images and texts and controls.
The slide show control at the top of the page shows 4 slides only. It looks like the loader is waiting for all contents of the page to be downloaded before showing the first slide of the slide show control at the top of the page.
My question is, is there a way to change the loader's behavior so that the 1st slide image of the slide show control at the top of the page appear first before loading all of the contents of the page so that while the visitors look at the first slide image of the page the rest of the contents of the page load?
I'm living in Australia and the internet speed here is extremely slow compared to other developed countries.
Please help, if possible.
Thank you :-)
