Title: Benchmarking OPNsense
Post by: fathibn on February 21, 2019, 10:19:50 am
Hi,
We have setup an OPNsense (now 19.1) as VM with captive portal and radius authentication against an independent radius server.
This firewall is connected to the internet via a mobile broadband router.
When it reaches ~40 simultaneous users, the servers nearly hangs and stops responding for a while.
I will have to buy a new server and would like to know, hardware people are running OPNsense on and simultaneous users they can allow to the internet.
I am not running any proxy, nor ssl inspection, nor suricata, ... just routing authenticated users to the internet.
TIA.

You should be able to increase resources for a VM fairly easily. Which one is your bottleneck?

I have a lot of warnings and critical messages from the underlying hypervisor about memory, swap usage, disk backlog, fifo errors, disk utilization, inbound packets dropped ratio, ...  and that is why i am asking about sizing.

Take a performance benchmark, increase RAM and move the VM to storage with more IOPS, test again?
