The Linux kernel page cache ALWAYS knows better. Fighting it brings only worse performance. Usage of fadvise() is wrong 9 out of 10 times. Removing the whole fs package brings a nice 100% speedup when running costly prune command. And that is measured on localhost, the improvement could be much bigger when using network with higher latency.
