<br>
<br>It only signs a few records at a time to avoid eating all your CPU (my
<br>server seems to average 53 records at a time, coincidentally). It spreads
<br>out re-signing according to the sig-validity-interval: by default it takes
<br>about 3 weeks to re-sign the zone completely. You can make it a sign in
<br>bigger chunks to some extent by increasing sig-signing-signatures and
<br>sig-signing-nodes, but there are other hard-coded parameters (related to
<br>jitter on signature times) which make these options less effective than
<br>you might expect.

<br>Tony.
