Database overhead on profiles with presence can get high. Putting phones that don't need presence (either on the phone or that phone being watched) on profiles without presence enabled will make a big difference. Keeping your register and subscription times very high (8 hrs maybe?), and spread out (not happening all at the same time, there are some settings to randomize this) will also make a big difference. Disk io on the db becomes an issue as you push this too far. In the end, testing is the best way too know when you are pushing it too far.<span></span><br><br>On Thursday, September 17, 2015, Yehavi Bourvine <<a href="mailto:yehavi.bourvine@gmail.com">yehavi.bourvine@gmail.com</a>> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="rtl"><div dir="ltr">Hello,<br><br></div><div dir="ltr"> We currently have over 500 extensions, most of them sharing the same profile which has presence enabled (since some of them need shared lines and BLFs).
