fio_deploy_dir: " tikv_data_dir /fio"
# fio randread iops
min_ssd_randread_iops: 400
# fio mixed randread and sequential write
min_ssd_mix_randread_iops: 100
min_ssd_mix_write_iops: 100
# fio mixed randread and sequential write lat
max_ssd_mix_randread_lat: 2500000
max_ssd_mix_write_lat: 300000
# fio test file size
benchmark_size: 10G
