X-BeenThere: linux-f2fs-devel@lists.sourceforge.net X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: linux-f2fs-devel-bounces@lists.sourceforge.net I am a new to F2FS and want to test a basic benchmark of F2FS. My environment is to create multiple fio threads(5 and 10) with blocksize 4K and 2MB to know how the performance is. And the results shows 4K is always better than 2MB. I originally thought 2MB is faster because it fits the segment size. So 4K always be fast is because F2FS process each IO of 4K? Even if blocksize sets to 2MB, it will divide it into multiple 4K units to process? thanks _______________________________________________ Linux-f2fs-devel mailing list Linux-f2fs-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
