I have LAGGs on other internal networks that are getting nearly line speed with an identical configuration. This is only a problem with connections to OPNsense. If I run iperf3 as a server on the OPNsense LAN interface and hit it with a Proxmox or Windows Server client same result i.e. If I run speedtest from a Proxmox or Windows Server connected through OPNsense the throughput ranges from 850Mbps to 1900Mbps i.e. If I run speedtest-cli from OPNsense I get throughput between 5 and 8 Gbps depending on the time of day. It all works, but here is what I'm finding: OPNsense and Proxmox/Windows servers LACP bond to the S4810s Thanks a lot for all the time passed to help me.I've got a LAN performance issue that I'm having problems isolating and I could really use some help.Ī simplified version of the infrastructure is set out in the diagram:ĭell R620, Dual Xeon E5-2680 v2 2.80GHz CPUs But thanks for the tips, I'll try it if flow to down again with OPNsense. (but params must perhaps be optimized or not the best choice).Īnd now the speedtest results are very very good all the time, even when using bridge in Proxmox (1200-2000 Mb/s down and 650-700 : I don't try IPFire because results are good now with OPNsense (and it have some extra features and a quiet good web interface). OPNsense is a VM in Proxmox with 'processor' params to 'host', 4Go RAM, 3 cores, network cards in bridge mode and VirtIO 'driver' (for LAN and WAN), uefi - disk with writeback discard iothread ssd option. I'll restart from scratch the installation of my Proxmox and OPNsense. So, it's impossible to have a good network speed when use the bridge with my Proxmox conf and I don't know why. Globally same results.īut, if I boot my laptop Proxmox server with a Debian live, the speedtest results are very very good (1200-2000 Mb/s down and 650-700 Mb/s). Tested with the bridge attached to OPNsense or to a Debian VM or when try the bridge directly in the Proxmox. If I test directly from the network card on the Proxmox results are quiet good (down 800-1000Mb/s up 550 Mb/s).īut if I test when using the bridge, the flow drops to (150-350 Mb/s up and down). Thanks for your help and sorry for the time to answers and : I'll try different speedtest on my Proxmox install and optimizations in OPNsense but problems comes from something in the Proxmox conf or install (results for download are not always reliable but for the up it seems to be good).
