I guess it might be roughly tens of minutes.

  Dear Anand ,
 Thank you very much for reply.
 Yeah, I do plan to install the KNOT DNS and have a test.
 And I just want to get a general idea about how fast it signs before
 getting hands dirty :)
 Best Regards!

 Hi Gao,
  Dear KNOT team,
 We're now considering an update on our zone signer and KNOT DNS  
 seems to be a
good choice.
 I looked through your documentation and do not see the performace
 data about signing big zones.
 When the zone has about 10 millions entries , how long will it take
 for KNOT DNS to sign it completely? 
 This depends on many things, such as the number of CPUs available, their
 clock frequency, signing algorithm, etc.
 Why don't you just install Knot on a test server, and configure it with
 your zone, and see how it takes? Then read the documentation about
 tuning some of the signing parameters, if you feel the need to improve
 performance.
