Expectations Of i3-4370 3.8GHz

Phantom_Stage

Can someone clue me in.
What speeds should I expect from a PfSense build using an i3-4370 3.8GHz processor and will I be able to run snort and PFBlocker NG along with some traffic shapeing?

It won't do 10G. Depends what you need.

As a vaguely close reference this is an i3 4160 (3.6G) running as an iperf3 server with 4 parallel streams. It's sinking at the port rate, ~940Mbps:

@stephenw10 Thanks Stephen...I don't need to do 10G...I just want to be able to do 1G pfblocker and snort with some traffic shaping. it will be going in a 1U chassis in a new rack I am building out was concerned about being able to do IG and traffic intrusion stuff,

stephenw10

Should be fine at 1G I would think.

@stephenw10 Awesome!
