Timeline for What could cause kvm virtualized pfsense to get 84mbps behind physical pfsense, but then drop to 1mbps when it replaces physical pfsense?

| Dec 27, 2017 at 23:09 | comment | added | neoakris | Thanks JFL I remember having to disable hardware acceleration/IPSEC offloading NIC features all the time when using Laptops with 16GB of ram as low power HyperV hosts. Specs say the 4 NIC ports are "Intel WG82583" aliexpress.com/item/… | |

| Dec 27, 2017 at 18:51 | comment | added | neoakris | I added configuration to question. Both boxes have bare bones default configurations, Eth1 = WAN via DHCP, Eth2 = LAN side configured for NAT. I'll check the NIC chip when I get home, good idea always hear bad things about Realtek, but could never map it to concrete reasoning. Are there Linux commands I can use to check port errors/duplex mismatch. Duplex mismatch is within the realm of possibility I know Gig Usually does duplex correctly, but pfsense bridge mode I know does asynchronous/half-duplex, I'm not sure if paravirtualization does half or full but a good path to follow up thanks. | |

| Dec 27, 2017 at 10:18 | comment | added | JFL | I see you plan to use VyOs. For information I do use VyOs on top of KVM (on Debian) and get very good performance (up to 40Gbs). I also have this setup on some ATOM box for small customers and no performance issue (but for 1gbs, not 40 of course). BUT I did have very poor performance with Realtek-based NIC. What is the NIC chip? | |
