Hello there, Seems like I hit another problem running FS 1.0.6 on EC2 - CPU usage by FS alone hits 65% for just one call! Here's output from top command: 26348 root 15 0 418m 42m 8024 S 65.8 0.6 808:37.18 freeswitch We use Rightscale image Centos 5.4 EBS and m1.large instance type. What can be possible reasons for that? I have never seen FS using more than 10% CPU for 50 calls on a regular box under Centos 5.2, we have version FS 1.0.5 there.
