Hi, I'm fiddling around with some compression options in fio but I don't seem to get it working. >From the fio manual, I see that the following options are supported by fio. buffer_compress_percentage, buffer_compress_chunk, buffer_pattern I have the following workload configuration, [global] randrepeat=1 ioengine=sync iodepth=64 iodepth_batch=16 direct=1 runtime=5 time_based=1 numjobs=1 verify_fatal=1 verify_dump=1 filename=./my_file [small_write] rw=rw blocksize=4k size=100M verify=crc32c-intel buffer_compress_percentage=50 buffer_pattern="abcd" With this, I don't see fio generating compressible data with the pattern and still reverts to generating random data. Anything I'm missing?
