<p>Again, sorry for veering off topic. I'll just say that I have
tried modifiying Asterisk source. Disabling AMI events helps only
a little, and disabling Newexten alltogether proved too difficult,
at least for someone with limited insight into inner workings of
Asterisk. If your dialplan is indeed 10k lines long, I am
reasonably certain you are getting frequent task processor
warnings in Asterisk log.</p>

I do use AMI for some things, but I have no use for the
"Newexten" and <br>
"Varset" AMI events (if I run my "amidump.php" script,
I'll see hundreds <br>
of these constantly even for a single call).<br>
<br>
In addition, it makes using core set debug >= 3 a real
pain, because <br>
then every complete AMI event is dumped, the result of
which is that 90% <br>
of the debug suddenly becomes an AMI dump of new exten and
new vars.<br>

<div>Stasis events can be disabled in stasis.conf, I don't
know the ramifications of disabling new exten but varset
is fine. Generating the stasis events is what can be
expensive.</div>
</div>

<p>Thanks, I'll play around with disabling both of them and see
how much that helps.</p>
<p>I see "ast_channel_varset_type" in stasis.conf - which one
would be the right one for disabling Newexten? I poked around
the code a bit but I'm not following the connection as much.<br>

<p>That's true (and I do filter) but AMI itself is still
processing the event, so it'll mean a waterfall of AMI dumps
with core set debug >= 3, and perhaps the overhead is still
significant for a large dialplan.</p>
<p>Disabling these two AMI events in particular, entirely, would
be nice. It seems like disabling the stasis events might take
care of that:</p>
<p>; Use of this functionality may break more complex
functionality in Asterisk<br>
; such as CEL, CDR, transfers, etc. and will likely cause
related messages in ARI<br>
; and AMI to go missing.</p>
<p>I don't use ARI at all - or CEL - so as long as CDR remains
intact, I could probably shut off a few of these...<br>

<div>Fair warning - things internally depend on snapshots.
Disabling them outright will likely break things.</div>

Got it, I wasn't as sure about this. I'll probably leave snapshots
alone for now.<br>
