Determining our throughput requirements

This recipe will explain how to determine the throughput requirements, and subsequently the processing and memory requirements needed in our environment.

Getting ready

We’ll want to prepare for determining our requirements by gathering the following information:

  • What connection speeds will our different types of users be expecting?

How to do it...

  1. Let’s review the general throughput and feature guidelines (available at http://pfsense.com/ at Hardware | Selection & Sizing):

    Firewall throughput

    Processing power required

    Server hardware (PCI-X/PCI-e NICs)

    10-20 Mbps

    266-MHz CPU

    No

    21-50 Mbps ...
