As I've written up in the thread we can not gain much from this optimization. The results of Jakub shows around 2% difference: >baseline, master, default Linux readahead (128kb): >33.979, 0.478 >35.137, 0.504 >34.649, 0.518> >master+patched, readahead disabled: >34.338, 0.528 >34.568, 0.575 >34.007, 1.136 >master+patched, readahead enabled (as default): >33.935, 0.523 >34.109, 0.501 >33.408, 0.557 On the other hand, the patch indeed is tiny and I don't think the proposed advise can ever make things bad. So, I've looked through the patch again and I agree it can be committed in the current state. Kind regards, Pavel Borisov, Supabase
