..._io problems really stand out. mount -o ssd option, which clusters file data writes together regardless of the directory the files belong to. There are a number of other performance tweaks for SSD, aimed at clustering metadata and data writes to better take advantage of the hardware. mount -o max_inline=size option, to override the default max inline file data size (default is 8k). Any value up to the leaf size is allowed (default 16k). Simple -ENOSPC handling. Emphasis on simple, but it prevents accidentally filling the disk most of the time. With enough threads/procs banging on things, y...

Hi, We did some performance test and found the create/delete files performance of btrfs is very poor. The test is that we create 50000 files and measure the file-create time first, and then delete these 50000 files and measure the file-delete time. (The attached file is the reproduce program) The result is following: (Unit: second) Create file performance BtrFS Ext4 Total times:
