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.
This is quite a lot, and the over 70 redirects they generate, e.g. to the following domains, are certainly not helping:
https://aa.agkn.com https://beacon.krxd.net https://cm.g.doubleclick.net https://d.agkn.com https://dpm.demdex.net https://e.nexac.com https://ei.rlcdn.com https://i.liadm.com https://ib.adnxs.com https://idsync.rlcdn.com https://io.narrative.io https://licensebuttons.net https://loadus.exelator.com https://p.adsymptotic.com https://pippio.com https://pixel.tapad.com https://pm.w55c.net https://rc.rlcdn.com https://secure.insightexpressai.com https://sp.adbrn.com https://stags.bluekai.com https://staticxx.facebook.com https://sync.mathtag.com https://tags.bluekai.com https://usermatch.krxd.net https://www.facebook.com https://x.bidswitch.net https://x.dlx.addthis.com
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 :-)
