Dear All,<br>
<br>
I'm having performance problems over HTTP with "-march=native" flag.
I'm sending you test results that I have made on the same hardware
and with same configuration.<br>
<br>
Suricata 3.0.1:<br>
* IPS<br>
* --enable-nfqueue --prefix=/usr --sysconfdir=/etc
--localstatedir=/var<br>
* <b>CFLAGS -g -O2 -march=native</b><br>
* workers mode<br>
* af_packet: threads: 16, cluster-type: cluster_cpu, use-mmap:
yes<br>
* threading: set-cpu-affinity: yes<br>
Intel Xeon CPU E5-2690 x 2<br>
Intel X540-AT2<br>
Ubuntu 14.04.4 LTS<br>
gcc version 4.8.4<br>
<br>
wget over Suricata: (results are consistent over many tests)<br>
1.784.676.352 55,1MB/s (single flow)<br>

Suricata 3.0.1:<br>

1.784.676.352 74,8MB/s (single flow)<br>
<br>
However there are no performance problems observed over iperf (tcp)
benchmarks in both tests. (~860 Mbit/s over single flow)<br>
<br>
Thanks.<br>
