Very interesting.  I had not yet heard of this.

Yes, this is known.  The least performance-inhibiting software that I 
have found so far is Norton Antivirus... it doesn't slow down 
Cygwin/XFree86, and it only has a minor affect (5% slowdown) on 
compiling Cygwin/XFree86 (which opens and closes thousands of files). 
On the other hand, Network Associates V Shield slows compiling down 
about 150% and generally makes the computer unusable.  Of course, I 
don't run antivirus software when not forced to, cause I don't do stupid 
things :)
