...why there is such a big performance decrease when using pci passthrough to mount the nvme disks. ive made a lot of changes to the vm but none of them seem to make any difference. I can only think theres some cpu scheduling issue but asside from setting cpu affinity im not sure what else i can do.

...disk to the slow disk (this data is hardly changing) --> is this possible? How? Ideally I'd like to assign a zfs dataset to have a certain affinity with a vdev, e.g. zfs create rpool/backups/data-tim -affinity /dev/sda such that it has a preferred vdev to write to. Is this possible? Any...

Ich bekomme Mails über Threads wo ich gepostet habe. Von diesem Thread habe ich keine Mail bekommen, außer heute zu diesem Post. Warum das Limit? 18 CPUs bei 16E und 8P Cores finde ich ungünstig. Da hast du garantiert immer verschiedene Cores in Nutzung. Außerdem, welche Anwendung braucht denn...

...Anzahl kommt durch die Threads zustande, verstehe ich. Sollte ich diese aber auch zuweisen, um maximale Performance zu erhalten? CPU Affinity zielt also auf die CPU nicht Cores (im Bezug auf den lscpu screenshot) ab. D.h. wenn ich eine VM mit CPU Affinity 0-15 starte, sollte sie alle...

When assigning affinity cores is it better to assign the first set of cores or the las set. Say my cpu has cores 0 - 31 is it better to set affinity to 0-3 or 28-31

Thank you for your response as of right now i have sockets set to 1 and cores set to 4 with affinity set to 1,3,5,7 with numa option enabled. This seems to give me the best performance with my opnsense vm. Running intrusion detection netflow and ntopng i still get the full 1gig from spectrum...

So i am using opnsense as a vm. With multiple rounds of testing i seem to be getting the best download speeds when using cpu affinity and only 4 cores. I pinned this vm to cores 1,3 ,5 and 7 since these are on numa node 1, the same node that the nic i am passing through is directly connected to...

...ps -aeF, I used ps -eLF. Now I have checked all VMs and it works they stay at the CPU I set. You don't need to specify specific cores for the VM you can just enter all the cores for CPU0 in CPU affinity on all VMs you want to run on CPU0 and the same for those you want to run only on CPU1...

If I use the easy approch with affinity in the CPU settings, I have 88 cores, 0-21, 44-65 CPU0 - 22-43, 66-87 CPU1 If I would set cpu affinity to 0-21, 44-65 for all VMs I want to run on CPU0 and 22-43, 66-87 for all VMs I want to run on CPU1 would that work ? I'm not interested to set...

...I do not want more than one C VM on a node when possible. I thought (PERHAPS MISTAKENLY) that an HA group was a 'purpose' construct, not a locality construct ... It felt like the wrong tool to use for conveying physical hardware affinity .... am I just totally misunderstanding the construct?

...always lie in managing idle states and NUMA. However, note that you can tune idle states on specific CPUs, and when combined with manual CPU affinity settings applied to the guest, this flexibility can help you achieve the desired outcome for VMs that need low latency. For what it's worth...

The VM will see them as all the same type of virtual core. You should not count hyper-threads as cores as they only give about 5%-25% extra performance in some workloads. You should not give many of your cores to a single VM and that increases latency and is not what a clustered enterprise...
