Performance issue after enabling IPS.

RPR84
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!

    Hi, are you testing one download, or multiple?

    Try multiple downloads, with 
    cc set ips num_instances 2 

    Also try disabling Content Detection or Application Detection or whatever it's called now.

    Are you using the HTTP Content Filter and AntiVirus?
