![]() The chelsio hardware (thanks jim!) and intel hardware (thanks To unsubscribe, send any mail to " so it's. I expected to see at least 2 threads working, say, for Threads on 8 CPU with 8 queues I still only see 1 thread working, all other ![]() I also looked on "pkt-gen -p 8 -c 8" and although debug shows I have 8 The bridge application, I can't have it working. However both opening ix0-1 and ix1-1 on source code or as a parameter to The 8 available queues allocated on each one of my 8 CPUs. To make it multithreaded, and I want to have a thread opening each one of I am asking this because I want to hack (for learning) into the bridge code So yeah, ix0 or ix0-0 both give me 14.8Mpps while any One single queue, sure, however if I run: I can understand if I run all queues I can have better pps rates than only In fact I have 11Mpps if I run on ix0-2, ix0-3. I could also notice performance differences I would like to understand, if Mr Pavel Odiltsov, the author from fastnetmon mentioned he can run on Linuxīut this or the above bridge example won't work on FreeBSD. Why is that? And how could I make something like this, work (code change I can transmit but cant receive on a given queue. On my tests I can see that "pkt-gen -f tx -i ix0-0" will work, but "pkt-gen Or something else happens, like, only 1 queue is used if I open netmap:ix0?Ī later question, if I open netmap:ix0-0 and nothing else is it supposed to Netmap:ix0 I have all queues from 0 to 7, is this understanding correct? This queue fills up the next packets will be on netmap:ix0-1, and via Themselves? I mean first packeds will be available on netmap:ix0-0 and if If open netmap:ix0 I am opening all 0-7 queues. For the small amount of traffic most all the drops were in software.I have some doubts regarding netmap design direct queue usage. This was never an issue for the linux/af_packet combination. Dropped packets are not logged by Suricata in netmap mode. Name Mtu Network Address Ipkts Ierrs Idrop Ibytes Opkts Oerrs Obytes Coll Drop Suricata was humming away, eve and dns logs scrolling. I configured Suricata to use netmap, and the monitor interface to come up at boot with “up -arp -rxcsum promisc” in rc.conf.

I bootstrapped the package system, configured pkg to use it moving forward, and installed the dependencies for Suricata. There are no FreeBSD-12 packages for arm64, but the binaries for 11 work just fine. dev/mmcsd0s1 /boot/efi msdosfs rw,noatime 0 0 I unmounted them and commented out of fstab. I assume this was an artifact of using growfs option in crochet. I also had some unnecessary mount points. The change was commited to crochet a few days ago so you might not have to follow the solution from Gonzo’s post. A google search lead me to a FreeBSD developer who has been working on the Pi3, and a blog post containing a quick solution. This error reads like an additional cpu can’t start.

Browsing traffic of a few people, mobile devices, streaming services, cat videos and garbage devices that clog up the tubes. Suricata is in af_packet mode, cluster type is cpu, and I have the ring size dialed in to comsume most of the systems memory. I run Suricata on a Raspberry Pi 3 at home.
