      Hi pfSense Gurus!

      We have pfSense installed on a old (born in 2014) server: PCIe 3.0 motherboard Intel C600 Series with 2xXeon 8-Core CPU with a 6 of PCIe v.3
      4 of x8 slots (dedicated to CPU 1)
      2 of x16 slots (dedicated to CPU 2)

      How impact mixing the 2-head NICs:
      Intel® I350-AM2 Powerwille based - 1Gb/s - PCIe 2.1
      ftp://ftp.kontron.com/Products/Accessories/EoL_Components/LAN_WLAN/DS_F5000-L004_Dual-LAN_D3035.pdf
      Intel® 82576EB Kawela based NICs - 1Gb/s - PCIe 2.0
      https://sp.ts.fujitsu.com/dmsp/Publications/public/ds-py-lan-adapter-d2735-2.pdf

      to overall network performance for delay/jitter sensitive applications like video/voice streaming?

      Is that CPU loading increases because higher IRQs numbers from NICs, etc... ?

      Tank You all for detailed answering!

        What CPUs are those? How much throughput?

        But I would expect almost no difference just in the slot ordering. Are you seeing something that makes you think it might be critical?

          I prefer asking from pro before making mistakes and waist a time. Especially in most known (I hope) questions. ;)

          I just make efforts to minimize all possible influence on a netflow.

            should not be an issue. that is massive overkill for pfsense. you can vm it and run a few other things on that (adguard home, etc)
