Is it just me or are most .onion domains really slow?
If its not just me then why is it slow?
Alot of domains seem to not work and a few work and are really slow...
.onion addresses are served using Tor Hidden Services and are known to be high-latency. There have been efforts to Speed Up Tor Hidden Services but they're still generally slower than "external" websites.
The NLnet Project: Speed Up Tor Hidden Services is a old project (2008 - 2009). You canot prevent loops but you can inprove the web server return. Did you try to serve hidden services using apache httpd, Nginx, Lighty or node.js?
