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.

    I've pinned this down, it appears to be the data control component.  With the data control turned on, as soon as I open Microsoft Outlook there is a big overhead on loading profile and SAV service jumps to 50% CPU utilisation (dual processor system).  There is a performance overhead on Internet Explorer as well.  Both of this issues evaporate when the data control is turned off.  I will leave this turned off tomorrow and see if I get a positive repsonse from users.  Trouble is the DLP features are highly desirable, but this performance overhead is unacceptable.
