During our performance testing of Sophos Endpoint Security and Control on Windows 2008, we discovered performance issues when more than ;5,000 endpoint computers are managed by Enterprise Console. At that time, we issued guidance that any installation of Enterprise Console on Windows 2008 should be supplemented by the installation of a message relay if more than 5,000 clients would be managed.
Following more in-depth investigation by Sophos, we have revised this limit to 4,000 endpoints. This revised limit is based on our analysis of customer environments and continued in-house testing.
Due to these issues when managing greater than 4,000 directly connected endpoints, Sophos highly recommends using Windows Server 2008 R2 or Windows Server 2003 R2 for the following roles:
