Title: Suricata 4.1 better performance then the 4.0 version?
Post by: xmichielx on January 08, 2019, 08:57:11 am

I see that the new 18.7.10 has Suricata 4.1.2 and was wondering if people find some performance differences with the former Suricata (4.0.*) version?
I already notices that the IPS performance was better with 4.0 over 3.* on an APU2C4 but am wondering if I should upgrade or wait for the 19.1 version which comes our later this month.

If you wait for 19.1 you can't compare the speed because 19.1 comes with a new kernel/OS (HardenendBSD 11.2) so you can't be sure if it was the OS or Suricata :)

We also have upcoming netmap changes later in 19.1.x and a Suricata netmap rework to look forward to...

Ha! Then I wait for the 19.1 version, will that also include the reworked netmap from Victor Julien?

PS, I am still very interested in some results or experiences with this new Suricata 4.1.2 version in regards to the older 4.0.* version from OPNsense users :)

Just update and test on you own. I dont think there will be a dramatic boost.

I've noticed not a big difference indeed, I do notice some new flowbit errors:

Not sure if this is an issue but the rest of rules work fine :)

Victors rework and the netmap help from Sensei guys will take a while to finish so for now it's just 4.1 and 11.2 in 19.1 to look forward too. The reset will be picked up on our way to 19.7 and beyond.
