I have an application that is generating HUGE amounts of dirty data.
Multiple GiB worth, and I'd like to allow it to fill at least half of my
RAM.
I already have /proc/sys/vm/dirty_ratio pegged at 80 and the background one
pegged at 50. RAM is 32GiB.
it appears to be butting heads with clean memory. How do I tell my system
to prefer using RAM to soak up writes instead of caching?
Atm I'm at the stage where I'm prepared to patch the kernel itself.
