Performance issue after enabling IPS.

Just we install Sophos Astaro UTM in our network environment. Now we have an issue when we enabling IPS. When we enable Intrusion Prevention, max download speed is 50Mbps. When we disable IPS, we can download with speed of 110Mbps.

We install Astaro Security Gateway as a virtual appliance in Hyper-V. The VM have 1GB internal memory and 1 CPU.

Is there someone that knows how I can solve this issue? Thanks!

IPS is single threaded so mhz matters more than core count. Also I have found that more than two vcpus means you won't get full performance out of all of the cores. Stick with 2 vcpus and load up the mhz.
