Is Symlink Race Condition Protection Needed on a Non-Shared Server?

I am trying to beef up security on my server, and hopefully not slow it down, as it is very busy.

I operate a dedicated server, and with the exception of temporary FTP/cpanel access to certain sites on the server, I am the only person who has access to the server, and any sites on it. In my case, do I need to worry about Symlink Race Condition Protection?

 

I don't see an answer to my question in that thread, but it looks like if I control all sites on my server, which I do, then the only way I need to worry about Symlink is if one of those sites gets hacked, is that correct?

PS - The reason not to run it is the warning about slow performance. I want fast performance.

 

Great, I applied the patch and hope it won't slow things down (I'll report it here if it does).

Second question moved to it's own thread - New Thread - Apache vhosts are not segmented
