Doing a quick test myself it looks like it’s mostly static content.
Maybe worth putting these files in CDN like AWS Cloudfront?
Some images on the landing page are half a MB.
Edit: Theres an image that’s 1.5MB
We have just done quite a big website refresh, so it’s possible that browser cache evictions are increasing page load times.
I will forward this to the web team to investigate.
Hmm, that might explain the OP’s issue.
But separately those are exceptionally large files, and there are quite a few of them on each page.
I would recommend at least having different resolution images for different display sizes, so mobile doesn’t load the full-size, larger resolution images. The new website is responsive already so it shouldn’t take too much work.
ImageOptim is a good app to reduce image file size and keeps the image exacicly the same since it romoves things like the image metadata.
Cloudinary is also very good for this.
