i am testing a very basic IMS core Kamailio-based using as HSS FHoSS. However, while using SIPp to stress the system, i noticed that the VM hosting the FHoSS is overloaded (even with 2 registration scenarios per second), in particular using top i was able to see that the java process used almost 200% of the CPU (i run the VM using qemu with options -m 1024 -smp 4). Is it normal or have i misconfigured something? Someone else has the same problem?
