  Tip: Optimise images

  1. main-building-alt1.jpg is 2.5MB
  2. earth-2.png is 200kB
  3. staticmap.jpg is 174kB
  4. screens-4.png is 164kB
  5. servers-1.png is 146kB
  6. home-header-bg.png is 110kB
  7. purple-cover-panel.png is 109kB
  8. servers-3.png is 103kB
  9. earth-4.png is 101kB

  First, check that images are appropriately sized - you most likely don't need a 6000x4000 pixel image straight from a digital camera. In Windows, the Photos software will let you quickly shrink huge images and will give you an improvement.

  Next you could try using tinyjpg.com (JPG image) or tinypng.com (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.

  *This is an estimate from Google PageSpeed and you may get much better results than this in practice.

  Tip: Large files

  Aside from images, here are the biggest resources:
