I wanted to run these results pass the group to see if anyone 
experienced the same.  Using the BIND 9.6.0-alpha that came out 
Monday, running on a laptop (for those who care about speed).

Starting with a 1 million delegation zone (n000000.tld to 
n999999.tld), consisting of about 2.1 million NS records, 2.1 million 
glue A records, and 1000 glue AAAA records, plus a handful more 
records at the apex.  Each has one KSK of RSASHA1 2048 and ZSK of 
RSASHA1 1024.

dnssec-signzone -g -o tld -f nsecsignedzone.tld -t -v 1 -k 
Ktld.+005+15178. nseckeyedzone.tld Ktld.+005+48162.

nsec3key is with alg 7, the *signed* are the results

Never confuse activity with progress.  Activity pays more.
