17.7 Legacy Series / DNS Resolver Slowness
« on: August 23, 2017, 06:58:42 am »
Hello All - finally upgraded to 17.7 and used a complete fresh re-install from the mirror. By default the DNS Resolver is enabled and the DNS Forwarder is disabled.
www.google.com for instance on the DNS Lookup screen when DNS Resolver is enabled shows:
Most of the times it's > 5k ms for the 127.0.0.1 lookup. Sometimes it shows no response and has all sorts of issues with internet.
Switching the DNS Resolver off and turning on DNS Forwarder (including using the ISPs DNS servers) works way better.
No additional settings were changed. Plus internet becomes more stable from the LAN ports with the lookup response times lower.
