<div dir="ltr">Hi,<div><br></div><div>@josh, We are using AGI. It is a very simple perl script. If we need to move to FastAGI we most likely would port it to ARI instead. But I let you know.<br></div><div><br></div><div>@john, we using Perl. To see if it is a problem with the perl i had put an "exit 0" just at the first lines so there is no logic done at the AGI. It's only the start up and return from AGI what produces the most of the load. Nevertheless, we will try what you just posted.<br></div><div><br></div><div>thanks for your help. I will keep you updated!</div><div><br></div><div>BR</div><div>Jöran</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Sep 20, 2019 at 7:38 PM Tech Support <<a href="mailto:asterisk@voipbusiness.us">asterisk@voipbusiness.us</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US"><div class="gmail-m_6532043458866211006WordSection1"><p class="MsoNormal" style="text-align:justify"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">Hello;<u></u><u></u></span></p><p class="MsoNormal" style="text-align:justify"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)"> What programming language are you using?

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. <u></u><u></u></span></p><p class="MsoNormal" style="margin-left:0.25in;text-align:justify"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)"><u></u> <u></u></span></p><p class="MsoNormal" style="margin-left:0.25in;text-align:justify"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">If you are using PHP, then I’m sure that the above still applies, but PHP is not my area of expertise. <u></u><u></u></span></p><p class="MsoNormal" style="text-align:justify"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)"><u></u> <u></u></span></p><p class="MsoNormal" style="text-align:justify"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">Regards;<u></u><u></u></span></p><p class="MsoNormal" style="text-align:justify"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">John V.<u></u><u></u></span></p><p class="MsoNormal" style="margin-left:0.25in;text-align:justify"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)"><u></u> <u></u></span></p><p class="MsoNormal"><b><span style="font-size:11pt;font-family:Calibri,sans-serif">From:</span></b><span style="font-size:11pt;font-family:Calibri,sans-serif"> asterisk-users <<a href="mailto:asterisk-users-bounces@lists.digium.com" target="_blank">asterisk-users-bounces@lists.digium.com</a>> <b>On Behalf Of </b>Jöran Vinzens<br><b>Sent:</b> Friday, September 20, 2019 12:47 PM<br><b>To:</b> Asterisk Users Mailing List - Non-Commercial Discussion <<a href="mailto:asterisk-users@lists.digium.com" target="_blank">asterisk-users@lists.digium.com</a>><br><b>Subject:</b> [asterisk-users] Load issues using AGI<u></u><u></u></span></p><p class="MsoNormal"><u></u> <u></u></p><div><p class="MsoNormal">Hi all,<u></u><u></u></p><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">we have just upgraded from Asterisk 11 to Asterisk 16.<u></u><u></u></p></div><div><p class="MsoNormal">After porting all the config to 16 we figured out some major load problems.<u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">the majority running of our Asterisk instances is still having Asterisk 11 so we can compare load handling on both versions.<u></u><u></u></p></div><div><p class="MsoNormal">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).<u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">Our asterisk is only handling Calls, so there are no Subscription no Registration etc.<u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">After some testing we figured out if we eliminate AGI Apps from Dialplan we reduce the load significantly.<u></u><u></u></p></div><div><p class="MsoNormal">At the moment we have 6 AGI calls for one single call.
