-If this is set, then fio will attempt to provide I/O buffer content (on
-WRITEs) that compresses to the specified level. Fio does this by providing a
-mix of random data and a fixed pattern. The fixed pattern is either zeros,

-is used, it might skew the compression ratio slightly. Note that this is per
-block size unit, see \fBbuffer_compress_chunk\fR for setting a finer granularity
