Performance on ESXi 6.5 (Supermicro A1SAi-2750F)
So, the saga of getting my pfSense firewall up and running continues. I was able to get my Supermicro A1SAi-2750F up and running with VMWare ESXi 6.5 and virtualizing the pfSense instance. I gave the VM 2 CPU’s and 4GB of RAM, thinking that would be sufficient. The system seems to run well, except the clients are bottlenecked to about 380mb up/down on my 1gigabit circuit. On my old router (the Unifi USG) I was getting about 900mb+, which seemed right, so I’m sure my service provider isn’t the problem. Could the issue be the CPU on this Supermicro mainboard? I got better performance out of an Intel i5 9400 based system, but the problem was on that system I couldn’t get ESXi to run on it, so I could only use Proxmox (not that this is a problem) and on that platform for some reason my download speeds were normal (about 900mb) but I couldn’t get my upload speeds over 700mb…and I wasn’t happy about that. I figured the Supermicro board would be a better choice.
So, do you think the bottleneck on this Supermicro platform is the CPU being the Intel Atom C2750? Seems like it should be more than sufficient to get gigabit speeds, but maybe there’s something I’m unaware of?
Have you tried bare metal? are you using any packages? It should be enough to do 1Gbit/s
@hugovsky Thanks. No, I haven't tried bare metal, I was really hoping to use this 8-Core server to do both pfSense and Virtual Servers (seems like it would be beefy enough). Is the consensus that pfSense isn't really going to see gigabit speeds in a virtualized environment?
Appreciate your feedback!
