<div class="moz-cite-prefix">Hi Olaf,<br>
<br>
As stated back in June we did took the snapshot and placed in
production on one server to test how it works. One month ago we
deployed that same snapshot on a second server as well. Till now
there is not a single issue and we get around 50 millions queries
per server within 24 hours for aboutn 300k zones.<br>
<br>
We also had a DDoS hitting our servers with ~800mbps and NSD
survived without issues. <br>
<br>
Note that we are not using dnssec and servers are runnig as
masters.<br>
<br>
So all in all we are very satisfied by NSD4 (even if it is not yet
the production release). Keep up the good work and i hope this
feedback is usefull to you and maybe for others.<br>
<br>
Best regards,<br>
Pavel<br>

Hello Pavel,<br>
<br>
We are currently shifting priorities in order to crank up the work
on NSD4.0 it is not very likely that you will see a production
release before end of year, albeit not impossible either.<br>
<br>
During the development process working snapshots (working, but
with limited functionality) will be published in SVN (See <a
moz-do-not-send="true"
href="http://www.nlnetlabs.nl/svn/nsd/tags/">http://www.nlnetlabs.nl/svn/nsd/tags/</a> ).
Obviously these snapshots are for the daring among you who want to
help us test in real world environments.<br>
<br>
Currently we are at snapshot 5. Now that might not mean a lot but
we have accomplished a few things:<br>
<br>
* Performance increase with radixtree and more optimal
compilation.<br>
* UDB on disk, removal of zonec. This means using editable disk
database with mmap.<br>
* NSEC3 prehash incremental<br>
* Patterns, new config file structures to manage many zones<br>
* Control, SSL remote control: output statistics, force zone
transfer, add and remove zones.<br>
<br>
The above is a cut-n-paste from internal notes and may not mean
very much. However, while maintaining the (stable) NSD3 query
logic we improved performance and added features that folk have
been waiting for: Addition and removal of zones without the need
of a restart. <br>
<br>
If you are daring to run the snapshot we appreciate any feedback
you may have.
