Hi @deibit,

I think every Intel Core with AES and 4 or more cores @3GHz or more is OK for OPNsense with Sensei and Elastic. In the incoming 1.5 you will have the option to choose backend database manually and this misunderstanding will be solved. May be it's good to upgrade cpu to non-L Haswell or Broadwell cpu for better VPN throughput. Also you have to know that for some strange reason Ubench rates Haswell Xeons way lower than non-xeon i5 on same clocks...

I "upgraded" to a E3-1268L that I had here "laying around". Now the ubench score is in the 342.000 range, I don't think it makes a big difference but my karma is again in balance due to sensei not complaining about my router being lower end :)

I still wonder why the single core performance is so important for elasticsearch though...

Hi,

I have just installed OPNsense after many (more than i recall) years using PfSense. One of the first things I installed is Sensei.. I liked it so much that I even paid for the home license :)

I run OPNsense in a SC813 Supermicro Rack, with a X10SLM+LN4F MoBo, 32GB DDR-1600 ECC RAM, a Xeon E3-1230L V3 CPU and a 2TB Seagate Ironwolf HDD (all baremetal, not virtualized).

I use a single 1.000/50 Mbit/s WAN, not many simultaneous webusers (4 or 5) but heavy traffic on the 4 VPN tunnels (fileserver)

The CPU gives 267.081 Single CPU Ubench index. So it's underpowered according to Sensei/Elasticsearch standards.

I guess I wouldn't have any problem in upgrading the CPU, but why is the single core performance so important? ElasticSearch s supposed to take advange of multiple cores isn't it? (CPU has 4 cores and 8 threads)

Should I be worried? Where can I look if my CPU is struggling? Everything "feels" good so far...
