Posting comment takes too long

It usually takes 5-10 seconds to post a single comment, its too long. 

I see in the console that it hits on recpatcha when I post, why?? 

When there is no challenge being shown, why hit it at all?

I suggest exploring possibilities to reduce recaptcha hits after a successful one. 

Like how cloudflare does it. They are really too fast at it, especially if you are not using a VPN. Even with one its a one click affair, over a long time.

You can configure the pain CF causes the user though. I do visit a site which is absolutely atrocious to use with it.
