Subject: [f2fs-dev] possible to allocate a full segment for a direct IO with blocksize 2MB?
Date: Fri, 10 Jul 2020 11:33:07 +0800 [thread overview]
Message-ID: <CAB3eZftzcywNU-cf7mRWqtj-74VqgzLHC32a6v_CycVcRsiu0A@mail.gmail.com> (raw)
I create 3 dd job write 1GB file with directIO and blocksize is 2MB
equal to segment size.
But it seems the each IO of three job's physical block address maybe
in different segment.
If I can get full segment for one directIO, I thought performance will be up.
Is that possible?
