In the test I just ran here you have .990ms as TTFB. Typically what I see on all of my sites is a target somewhere around 240-350ms, and 'A' grades for this follow. You're never going to have a TTFB of 168ms. It's unattainable. Unless of course you're just loading blank pages. The target FBT will be a much more realistic number once you completely get rid of CF, and so will the total FBT you actually get.
TTFB of 150ms or even below 100ms is definitely something attainable. It might be tricky, complex and expensive but you can achieve it.

RE: Slow Time to First Byte,
I've done some testing, and have to admit, I had a hard time telling the difference between a well-compressed and optimized image and a "high-quality" jpeg image. I worked as photographer in the past and have tended to err on the side of high quality, but the images are larger now and there are a lot more of them.

As for Cloudflare, I'm trying a different host that specializes in Wordpress. The site hasn't gone live, but so far the TTFB has been an "A" on two out of three tests vs. always an "F" previously.

Thanks for all the help.

Wow, imagine that. You're welcome.

Sites not running CDNs don't get these ridiculous target FBT numbers. And they are ridiculous. When I said "not attainable" what I mean is, reasonably so. As you just said, it's not reasonably attainable.

But when you remove the CDN, the target assigned is a much more reasonable and attainable number, and like magic, the grade improves.
