I use Cloudflare for affLIFT, my blog, and a bunch of other sites.
For pop traffic, Aaron recommended not using it because it can slow down the click speed. He gave me a bunch of technical reasons which I am not sure I fully understand yet, but recommended I use the default domain he had already provided instead for this test. I trust his judgement on it so I went with it.
@Kintura maybe you should make a thread explaining why it’s better to not use Cloudflare with more detail?
