Lightweight Sensei setup for smaller CPU (i3 4100U)

[ArminF]

Hello All,

is there a way to run a lightweight setup for sensei?
I do have an intel i3 4100u 1.8 GhZ SOC CPU.
As soon as i install sensei my system crashes and i have to uninstall sensei through console.

The setup detects my CPU as (orange) i guess weak and give me a green on 8 GB memory.
Nevertheless my system crashes afterwards. No dhcp actually none of the services are started.
Starting them through console ends with an could not start mongodb.

i would be able to choose from mongodb or elasticsearch where default is set to mongo.

Beside i do run cryptDNS maybe this could be an issue as well.
WAN is 250 MBit and 25 upload.
4 Intel NIC each 1GB

i would really love to run application scanning on the LAN side.
Or is there maybe another tool which would run with less resources on opnsense?

Any thoughs or tips?
much appreciated!
thanks
