Your banner is a bit too large (50% of your site), and since it's the first image that loads, the performance isn't very nice in uncucked locations (outside of SoCal). I am providing a webp version, you should not delete the original, because you should move to avif in the future. It's 20x smaller. https://s1.fileditch.ch/ipYuZQwFobmRtTCymfH.webp
webp is a google tracking format.
but png is a laggy format
Ill try to make it better, thanks for help.
you can use mozjpeg if you want, but getting the encoder up and running is more involved for me whereas gimp had built-in support for webp encoding
