Hi, everyone I am writing to ask if the recently introduced RWF_DONTCACHE [0] (originally named RWF_UNCACHE) in the Linux kernel will be or is already supported by PostgreSQL?
I am not sure if RWF_DONTCACHE will improve PostgreSQL performance. In fact, I think it may even degrade performance. Has anyone tested this? [0] https://lwn.net/ml/all/[email protected]/ Thanks, everyone. Jinliang Zheng :)
