<div class="moz-cite-prefix"><tt>Hi Nash,<br>
<br>
It is somewhere in the middle :). Of course the DB ops will
bring some penalties to the performance, so you need to take
care and tune your DB for the best performance (not to drag down
opensips). With db ops is very common in OpenSIPS scripts, so
you do not do anything crazy or stupid there.<br>
<br>
Of course, you should look into optimizing the DB ops you use:<br>
- DB auth - use caching at script level (see
<a class="moz-txt-link-freetext" href="http://www.opensips.org/Documentation/Tutorials-MemoryCaching">http://www.opensips.org/Documentation/Tutorials-MemoryCaching</a>)<br>
- ACC - consider using db_flatstore to avoid writing into a
real DB<br>
- dialog - if not really a must use db modes 2 or 3

<div>I have used opensips for load balancing and some
border proxy+ NAT+rtpproxy in past and am quite happy
with it. Recently I decided to add DB operations (Auth
and accounting, routing and dialog into it so that
heavy lifting of VOIP network can be given to
opensips. I wanted to send call to PBX only when it is
really needed (Like voicemail and conference etc)<br>
<br>
</div>
But in a long time I saw this article <a

href="http://www.opensips.org/Documentation/TroubleShooting-FindPerfPb">http://www.opensips.org/Documentation/TroubleShooting-FindPerfPb</a>
<br>

As per this tutorial I think if any DB operation is slow,
it will hit overall performance (I mean the transactions
which do not require DB can also be stuck).<br>
<br>
</div>
I know good engineers at openisps have already figured it
out and working on 2.X version but looks like it will take a
while so that I can give it a try (As dialog is not in
current release).<br>
<br>
</div>
With 1.X series + DB auth/acc + dialog should I reconsider my
approach or there are systems running successfully and I am
just being paranoid?<br>
