I could confirm the results posted by Ayush Sharma (and featured on HN) regarding the large performance hit a website takes when loading Disqus comments, apparently because they collaborate closely with some user-tracking ads company.
This page, for example, loads 10 times slower when tested with GTmetrix (not sure how objective this is): 0.7
seconds vs. 7.2
seconds.
This is quite a lot, and the over 70 redirects they generate, e.g. to the following domains, are certainly not helping:

This is on top of all the privacy and security implications, and since nobody comments here anyway I will just disable them.
If you absolutely need to tell me I’m wrong, you can just write an e-mail :-)
