<p class="MsoNormal">CPU Pinning was the most impactful for our environment with similar traffic rates per box. The other was to address any stats that showed Suricata hitting any memcaps.<o:p></o:p></p>

<p class="MsoNormal">On test boxes I’ve tested CPU isolation and didn’t see a significant improvement. Hyperscan was helpful, and using Google’s TCMALLOC may reduce the memory footprint

<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> I am working on a new Suricata server (Dell PowerEdge R710, 72 Gb of memory, 2 6 core procs) using a Myricom 10 card running snf v3. It needs to process between 3 and 6 Gb of traffic fed by a NetOptics agg tap.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Currently the system is dropping about 10% of the packets and the SNF drop ring is full so that implies that Suricata is not keeping up with processing. I currently have 20 threads running and about 16 Gb of free memory.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> I have read SEPTun, SEPTun-Mark-II, the Suricata docs, the Myricom user guide, Peter Manev old blogs, etc…
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> And what I want to know is what performance tuning options have the greatest impact? Outside of buying faster processors, more memory or a different nic card.
<span style="font-family:Wingdings">J</span><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Is it the suricata.yaml configuration options?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Is it hyperscan?<o:p></o:p></p>

<p class="MsoNormal"> Sysctl settings?<o:p></o:p></p>

<p class="MsoNormal"> BIOS setting?<o:p></o:p></p>
