Specs needed for a build for a google fiber WAN using HOME use version"?

I am going to be getting Google fiber at my house soon and would like to put together a server build to run the home version of Sophos that will be able to handle the full gigabit of up and down speed I will have while still using the antivirus and intrusion prevention features. I currently have a 100 Mb connection and am using an older sonic wall but even this goes down to 70 MB whenever I turn on the gateway antivirus and intrusion prevention so there is no way it will handle my new connection.

  • Hi chriswise,

    I've read a number of threads in this and previous Astaro forum and have never found a config that was able to deliver a full Gbps throughput with IPS and AV turned on when installed on commodity hardware.

    I've tried esxi and hyper-v installs on dual quad core 2.66Ghz Zeon CPUs and didn't break the 300Mbps speed no matter how much system resources were allocated.

    I ended-up with a pair of Dell PowerEdge R210 II with Xeon E3-1270 CPUs and 16GB RAM with SSDs running in active/passive HA for my home. I installed Sophos UTM Home on baremetal to maximize use of machine resources. Since I don't have the number of concurrent users to take full advantage of a Gbps fiber connection, I've dropped my home speed to 300/100 Mbps. With this hardware I can easily achieve the full 300 Mbps speeds with the hardware not even breaking a sweat. Even with 3-10 concurrent users streaming content, that 300 Mbps connection is never saturated.

    At the end of the day, the single-threaded nature of Snort will likely mean that you'll never get a full single user speed beyond 300-400Mbps. In a multi-user environment, I'm sure that is different. I'm willing for someone else to correct me if I'm wrong but that appears to be the common refrain in these forums.
