<br>To give you an example I have a Dell R710 with two quad core E5520 processors running Asterisk 1.8 and FreePBX 2.11. I have around 1,000 SIP device registrations, 50-80 concurrent calls for the majority of the day, and a total of 8-10k calls processed per day. A few times a week I will see the last minute load at 20 and the 5 min load at 7. This seem to happen when there are a high volume of new calls as the FreePBX dialplan is complex.<br>
