Looking for advice to 'more better' use my VM Sophos setup

Hi. I've been lurking, searching, and reading for a while now and thanks to everyone for the hundreds of great posts that got me here. I would love some pointers to help make my setup more efficient / faster. I just built it this week and I have plenty of time to re-do everything.  I currently have Sophos UTM 9.4 up and running on the following hardware:

Dell R710, dual E5640 Xeon's (4 cores each at 2.66Mhz for a total of 8 cores), two 146gb 15k SAS cheetas running in Raid 1 (hardware Perc 6/i) for backup purposes (probably not necessary but seemed like the thing to do at the time), 24GB Ram, with 4 integrated Broadcom NIC's. My internet is 300 down / 100 up.

My setup:

I'm running Proxmox as my hyper visor and have given the Sophos UTM VM 6 processors, 12 GB Ram, 40 GB disk space, 1 dedicated NIC for WAN, 1 virtual bridged for LAN (so as to share the virtual switch with LXC containers on the same server).

Just today I read that I need to bump my HD storage up to 80 GB. I don't know how I missed that on the first go around but I'd rather fix it now and this is what got me wanting to post for anything else I missed. I saw several threads that refer to the legendary SNORT thread, a few mention dropping the number of processors to 2 but most of these threads were a few years old. Is this still the best idea? Is there anything else I should change for optimal performance? I plan to leave IPS turned 'on' if at all possible as this is one of the selling points of SUTM in my limited view. All comments are welcome, thanks in advance.

  • With Proxmox, using '2' cpu's in the basic set did not work; UTM refused to startup. In the end I was able to get everything working rather well (with pretty much everything turned ON) using the following:

    • Memory  8 GB
    • Processors:  8 (2 sockets, 4 cores) [vcpus=2] 
    • Hard Disk: 80 GB

    Everything purrs like a kitten. Now to fiddle around with my rules :)
