TWEAKS FOR REMOVING RSS FEED SYNC
Since a server is probably not syncing RSS feeds, there's a task that runs in the background that is not needed on the server.  In some cases you may see an alert in the event logs that indicate that the rss sync has not completed.  While it can be ignored, you can also adjust the rss feed sync to not occur.   This tip is courtesy of Yves Gourle:
You can disable the automatic feed sync as follows:

• Run the following command (with a command prompt started with elevated rights) : msfeedssync disable
• Or in IE options go to content  -feeds and web slices,  click on settings  and uncheck “automatically check for feeds”
