One other thing. I use a package called AGISpeedy. Its available for both
Perl and PHP and I’ve used it for years without any problems. Its supposedly an
order of magnitude faster than regular FastAGI scripts. The only downside is
that it hasn’t been maintained a while, but the package is solid and really
doesn’t need much maintaining. I’ll probably write the author and see if I can
keep it updated for him.

Subject: Re: [asterisk-users] Load issues using AGI
Hello;
What programming language are you using? If you are using Perl, then I can
suggest this.
(1) You are going to have to profile your scripts. This is a must. Without
profiling, you don’t know what the problem is. In my opinion, Devel::NYTProf is
the king of that hill. It could be as simple as optimizing a single subroutine.
Then you will know exactly what the problem is.
(2) See which version of Perl are you running and see if upgrading it solves
your problems. The easiest way is to download the newest Perl they support from
ActiveState.com. It creates a completely independent installation in /opt which
will not interfere with your system Perl. You can also compile and install the
newest Perl from source completely separate from your system Perl. That’s what
I do. I have a couple of scripts to automate that process. If you first get a
list of your installed modules using ‘perlmod’, you can clean up the output a
bit and pipe that to cpanm to make sure that you have all the modules you need.
If you are using PHP, then I’m sure that the above still applies, but PHP is
not my area of expertise.

Subject: [asterisk-users] Load issues using AGI
Hi all,
we have just upgraded from Asterisk 11 to Asterisk 16.
After porting all the config to 16 we figured out some major load problems.
the majority running of our Asterisk instances is still having Asterisk 11 so
we can compare load handling on both versions.
On the same hardware configuration we see load differences that Asterisk 16
takes four times the load as Asterisk 11 (on 11 we see load 0.5, on 16 we see
something around 2).
Our asterisk is only handling Calls, so there are no Subscription no
Registration etc.
After some testing we figured out if we eliminate AGI Apps from Dialplan we
reduce the load significantly.
At the moment we have 6 AGI calls for one single call. If we eliminate 3 of
them we reduce the load by half.
I also tried to have the AGI replaced by some fake AGI which returns
immediately to make sure it is not related to long running AGI Scripts but this
made no difference.
I tried to tweaked a bit manipulating the thread limitations in stasis.conf but
it had no significant effect on load.
Also I tried to "decline" all non AGI messages in stasis.conf. It seems it has
very little effect.
Does anyone have similar issues or a solution?
Is there anyone who calls AGI several times during call establishment?
any hin and help would be very much appreciated!
I am happy to share more config and information if it helps to find a solution.
