When running Sophos Anti-Virus with the on-access scanner enabled on a Citrix Server there is a degredation in performance as the number of endpoint computers connecting to the server increases.

The CPU usage for the SAVservice.exe process will spike and only a small number of computers will be able to connect to the server e.g., 15-25 clients.
