    With IPS turned on your expected to take a hit on performance - up to 50% from what I've been told from support in the past.  Which appliance is this or is the UTM running as a virtual machine or installed on custom hardware?

    You can also tune IPS using the Attack Patterns tab.  Uncheck the items that don't apply to your network - for example if you don't have Apache running, why enable the IPS scan for it and take up resources?  Go through that list and uncheck all the unrelated items for your environment and test again.  You can also change the Rule age down to 6 months from 12 months and see if that makes a difference.

    It is Sophos SG 330 harware unit.

    Isn't it the case, that i have IPS ON, but configure some exceptions (IPS exceptions) and then traffic should not be reduced when using those exceptions?
