Hi Yalkrif,

 

 

Is the iRule CMP compatible? If not, that would explain why the first core has higher utilization. You can check using:

 

 

tmsh show ltm virtual VS_NAME |grep -i cmp

 

CMP : enabled

 

CMP Mode : all-cpus

 

 

If that's not it, what process(es) does top show running with high CPU utilization on CPU0?
