I just did a virtual machine ESXi install from the VI-SFOS_17.0.0_GA.VMW-80 virtual image that sophos has on their website using the default values (1 cpu, 2 GB RAM, SSD disk). I configured all protection on as part of install. I ran a speediest, and:
- my download speed went down from up to 350Mbps using pfsense and squid to 30Mbps running on the same virtual server.
I then increased CPU to 4 (on a xeon 3ghz machine) and memory to 4 GB.
My speed went up to:
- 75Mbps, and CPU utilization based on the control center maxed out at 11%.
- I disabled ALL scans, and my speed was 280/350 max.
So, I redid an install from scratch on another VM with 4 CPUs and 4GB. Same performance as from imageVM.
I then installed to a dedicated fanless i5 router box (4 core, 4GB, 30 GBSSD)- another machine. Without scans, I was able to get my full speed (350/350). With scans, I only get 40/350. Again, CPU utilization is around the 10% mark.
Questions:
1. Why doesn't the CPU max out?
2. Does 32bits limit performance?
3. Why on a VM it doesn't hit 350 when all security is off
4. why it can only deliver 40/350Mbps with all protection on and why it doesn't use full potential of CPU
