Concurrent querying of multiple DNS servers

[sergeevabc]

Dear Frank @jedisct1,

At present DNSCrypt default load-balancing strategy is p2. This means sorting the specified list of DNS servers by response speed, selecting the two fastest, and then querying one of them randomly. Thus, only one DNS server is queried at a time. However, for example, Technitium DNS queries not one, but both of the fastest DNS servers concurrently and uses the response that comes faster.

What is your opinion about this feature?

Many servers are run by volunteers who pay for them out of their own pockets. By doing this, you're effectively doubling the traffic to those servers, even though half of it will be ignored. It's wasteful and extremely selfish. Don't do it.
