Ask HN: What cloudflare settings do you use?

And what pros or cons do you see by using them?

I just signed up for the $20/mo plan and am scratching my head as to what to pick for "Security" and "Performance" options at the end of the signup page.

The options for Performance are:

- CDN ONLY

- CDN + Basic optimizations (faster)

- CDN + Full optimizations (bleeding edge speed)

And the options for Security are:

- Essentially Off

- Low

- Medium

- High

I chose the highest security and the full optimizations as I figure I may as well get what I paid for. I am a little worried about the mention of possible captchas for accessing my site, however.
