Performance is horrible with cloud flare enabled

I have a paid subscription to Cloudflare for my photo hosting site. As soon as i enable Cloudflare, load time on the pages go from 800ms on a page with many images to over 7000ms ( 7 seconds ) this is really unacceptable. I have provided har files for the page loading with and without Cloudflare enabled and the load time on both for comparison. still waiting for results. But the load time on the images seem comparable. it’s all the other loads that are consuming the time. css, js, and a few others that with Cloudflare off load in 0 ms.

as anyone had similar issues? If so have they been resolved? On a pro photo hosting site, I cannot compress images, remove exif info etc … otherwise, no value to the site.

Thanks
