jdk8 build times

[Kelly O'Hair]

Peter,

It might be important for you to make sure the boot jdk image, and all tools used to build (like VS2010) also in the ignore list. Maybe CYGWIN too.
The boot jdk rt.jar file in particular can be slow to virus scan.
It kind of depends on how smart (or not) the virus scanner is on re-scanning already scanned files.
