I have tracked your IO trace log, I found an issue which may slow down our App, so I wrote the patch to optimize the flow mainly for SMR drive. I think we can tune up with /sys/fs/f2fs/(device)/ra_nid_pages to avoid long latency of creating node in f2fs. If you want to have a test with the new tunable parameter, last git tree is preferred. :) Thanks, > > -- > The choice of a Deliantra, the free code+content MORPG > -----==- _GNU_ http://www.deliantra.net > ----==-- _ generation > ---==---(_)__ __ ____ __ Marc Lehmann > --==---/ / _ \/ // /\ \/ / [email protected] > -=====/_/_//_/\_,_/ /_/\_\ > > ------------------------------------------------------------------------------ > _______________________________________________ > Linux-f2fs-devel mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel ------------------------------------------------------------------------------ _______________________________________________ Linux-f2fs-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
