Firstly I want to discuss the usage we saw In the session which was on average 48%. We talked about the fact that we have determined that the root cause for the high CPU usage is in fact the traffic and that there are several factors we concluded this from:
• In top, we can see that the SI or software interrupts counter increases in relation to the CPU usage, this usually indicates that the CPU is processing a certain amount of traffic
• In the peak times we have more traffic and the CPU is higher(70%-80%), this reinforces the fact that the machine is functioning as it should with more traffic and higher CPU.
