buffer_compress_chunk=int See buffer_compress_percentage. This setting allows fio to manage how big the ranges of random data and zeroed data is. Without this set, fio will provide buffer_compress_percentage of blocksize random data, followed by the remaining zeroed. With this set to some chu...
fio will provide buffer_compress_percentage of blocksize random data, followed by the remaining zeroed. With this set to some chunk size smaller than the block size, fio can alternate random and zeroed data throughout the IO buffer.
<21>buffer_compress_chunk=int 参见buffer_compress_percentage。 该设置允许管理随机数据和归零数据的范围有多大。 如果没有此设置,则fio将提供blocksize随机数据的buffer_compress_percentage,然后是剩余的零。 由于此设置的块大小小于块大小,因此可以在整个I / O缓冲区中交替发送数据和将数据清零。 <22>file_servic...

buffer_compress_chunk=int This setting allows fio to manage how big the random/fixed data region is when using buffer_compress_percentage. When buffer_compress_chunk is set to some non-zero value smaller than the block size, fio can repeat the random/fixed region throughout the I/O buffer ...
