Hello

I migrated to proxmox ve over a year now from hyperv and I just love the product. I have small home system running one single proxmox on Intel Core i5 with 16 GB RAM.

I have firewall and few other vms running.https://100001.onl/ https://1921681254.mx/ https://acc.onl/hotmail

Everything was working fine before I moved to pfsense firewall. With Proxmox, pfsense throughput dropped quite badly. I have gone through Proxmox and Netgate suggested settings and turned off all Hardware offloading. It has fixed the upload but still have slow internet speed. I have 300 Mbps up down link and I get around 150 with pfsense. PFSense vm has 2 cores and 4 GB RAM. Hardware usage are quite low.

I also tried spinning fresh PFSense VM and even tried PFSENSE developer build 2.5 but same problem.

I have Intel Gigabit nic. I tried using all network adapter options from Proxmox VirtIO, Intel E1000, VMware and even realteck one but no help.

I also tried other forum post suggesting disable TX on vmbr0 and actual ethernet port in /etc/network/interfaces but no help.

I can tell its not Proxmox issue as if I spin up Untangle vm, I get full throughput. I read somewhere FreeBSD does not work well with proxmox. When I use pfsense in dedicated hardware or Hyperv, it works just fine. I guess it has to do with the FreeBSD.
