Fresh install, very slow

[dschlic1]

I am in the process of testing different platforms for a security appliance/router for my home network. I downloaded the DVD version of OPNsense and created a new VM with one core, 4 GB ram and 32 GB disk. I did the standard setup, letting the WAN to be on my home subnet with DHCP and the LAN side on a different subnet. I have a Win 7 Pro VM which I use to monitor and test OPNsense VM. I updated both the firmware and also the rules for the intrusion detection.

I have a 50/50 internet service. The first test I performed was a speed test from within the Win 7 machine. Absolutely terrible, about 10% of what I should be getting. I then disabled the intrusion detection, and the result was better but still the CPU was maxed out. Without and traffic CPU usage is running about 50%!

Any ideas as how to find out what is going on?

Hi, what is the exact make and model of your CPU?  I have had no problems with running a single core on a i5-5250U mobile processor and 512MB of RAM without IDS.

If you want to use IDS then you would would at least have 2 cores on a CPU with good single thread performance.

Also what hypervisor are you using?
