Sophos on Citrix high cpu utilisation

ajsmith

I am finding significant performance problems with Sophos on our Citrix Xenapp 5 presentation servers (W2k3).  I have recently been seeing very high CPU utilisation - 50%+ for prolonged periods which is killing performance on the servers.  I have a seperate policy for the Citrix servers which includes windows exclusions for the Citrix program folder, UNC for roaming profiles, and the page file drive.  Can anyone share best practice for a successful deployment on Citrix or experience of similar problems and how they can be overcome?

Thanks.

    Good to know you might have found the culprit.  I would maybe link a new DataC policy to the group with maybe just one rule and see how that goes, then slowly add them back until you experience the problem.  Hopefully it's just one rule/CCL that could be tweaked or an exclusion applied.

    Are they all Sophos rules or are some of the rules you have made up of your own CCLs?
