Ok, so I've got my Sophos/Astaro all set up, running as one VM alongside another VM which is my Windows Server 2012 (my DNS/DHCP/etc). These are the only two applications running on this dedicate PC. It's got an Intel Core 2 Quad CPU @ 2.4GHz, 8GB RAM and a 64-bit O/S. I have 1Gbps NICs installed and all network hardware/cables are 1Gbps compatible from the fiber optic box & router all the way to my sophos/astaro box.
I just upgraded my FIOS from 60/30 Mbps to 150/75 Mbps. While I didn't really notice it before the upgrade, the IPS feature is pretty resource intensive - it slows down my network to 30/40 Mbps (I presume I'm getting better upload speeds than download speeds because an IPS doesn't care what you send, but does more critical processing of packets received). When I flip the IPS off, I get the speed I'm paying for.
So my question is this... How do I realize these great new speeds and still use my Sophos/Astaro with IPS? Would upgrading the PC to the latest chip (4th gen i7) and 32GB of RAM make a material difference? I'm hesitant to spend $1500 on a new box if there's a chance it's not going to make a material difference...
Appreciate any advice anyone can offer, especially if you've seen this problem yourself and fixed it.
Cheers
