<p>Does anybody use IRQBalance to ballance interrupts for nic processing?</p>
<p>I have set up IRQBalance service (in CentOS).</p>
<p>After viewing stats in /proc/interrupts, I feel like it is not working.</p>

It looks like only one CPU is doing the work here. Am I correct?
<p></p>
<p>In the past I have tried configuring affinity in Suricata config and had hard time since Packet Loss would even get worse.</p>
<p>Are there any guides on how to configure CPU interrupts for Suricata? I feel like I am loosing performance here.</p>

<p>Thank you.</p>
