Interesting, I'm starting to think that a lot of these performance issues people are seeing with 8.4.1 are related to this feature. I remember when tweaking in 8.3 turning off flushes improved latency dramatically. I wonder if there is a patch for the source out there? Maybe I'll consult the dev list to locate the spot in the code where this decision gets made and hard code turning off barrier and flushes.
