Interesting. Didn't know it could be turned off more effectively. 
Unfortunately, that doesn't fix all of the slowdown KPF causes for me. I 
think the program file checksumming done in the application behavior 
blocking causes the rest (making my test case take almost twice as long 
to run, even with the behavior blocking turned off). Didn't find any 
service to really disable that.
