You're putting words in my mouth. I merely pointed out that the reCAPTCHA page is not in any way a bandwidth hog. Whether you think captchas are an appropriate tool to filter out abuse from Tor users is a different discussion altogether, my point is that if you're going to have any kind of captcha, then the one CloudFlare is using is probably smaller in size than most other pages you might visit.

- mirimir 11y agoIt's not so much a bandwidth hog as a request hog.
- throwaway2048 11y agothis is a crucial point, new domains mean setting up new circuits, which is the real delay here. Its like the http blocking load RTT problem magnified by 10.
- pfg 11y agoAFAIK TBB doesn't create per-domain circuits for every subresource on a site (that would kill performance on many sites with 10s of third-party trackers, CDN hosts, etc.), but rather one circuit per "URL-bar domain". That domain doesn't change when a CloudFlare site renders reCAPTCHA.
