Hallo and thank you for choosing our work!
For better site performance please follow some simple steps
1. Images should be less than 500kb. For slider images you can use 1200X900 size for other images 600X400, 800X400 will be enough.
   Use this link for images compression - http://compressjpeg.com/
   Please watch video on manual compression for images. Quality vs Size control yourself as you wish.
2. Dont use two different animation on one page, that can affect site performance. Off course you can do that but test if that changes the site performance at first .
Thank you!
