h1 text taking a long time to load

Hi all,

PageSpeed Insights is telling me that the regular old heading I have on my homepage is killing the load speed.
Could anyone help me work out why that could be?
Is it because I have the text set to scale (fill the box)?
Insights is only reporting it as an issue on mobile too - if that makes a difference.

My site is: www.prettygoodsurf.com.au

Attached screen shots to help explain further.

Thanks
Adam
