  Tip: Optimise images

  1. 4e673db5587a1903ad58... is 190kB

  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:

  1. application2.js?v=1701291289476 is 319kB
  2. player.module.js is 134kB ×2
  3. vendor.module.js is 101kB ×2
  4. gtm.js?id=GTM-52FT2N is 96kB
  5. js?id=G-1X5CTQK0Z0&l=dataLayer... is 92kB
  6. ng.js?v=1.0.53 is 87kB
  7. allScripts.min.js?v=1.0.53 is 81kB

  There are 2 duplicate resources included on the page.

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Vimeo uses 566kB
  2. Olark uses 458kB
  3. Google Tag Manager uses 187kB
  4. Facebook uses 95kB
  5. Azure Web Services uses 767kB
  6. Bootstrap CDN uses 86kB

  Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
