not sure what the problem is, image loading?

[dark_night]

experiencing slow image loading on my forum on refresh, specifically for avatars. have cdn on images, cloudflare pro, redis caching, lazy loading, quick vps, but experiencing this even on default theme, whenever im refreshing and there is new content then the avatar is delayed a few seconds before showing. i dont use many addons either so dont think an addon is affecting it. have also tried doing research but seems like its not a issue thats widely talked about, anyone have any suggestions on what i can do that i havent already tried? out of options now .. or is it normal? only happens with custom uploaded avatars, but default avatar no issues ever

i also noticed, if the avatar is shown on the page before refresh, and u refresh then loading is not an issue anymore, only to new avatars that havejust popped up on a new refresh
