I was trying to exchange protobuf to gogoprotobuf, because I want to use gofast tool. I used fio tool to test disk I/O. I found it only have 1/7 of the host disk. I sent only one I/O test per request.
My executed command as follows:
fio --filename=/root/test-fio-w/test-big
--direct=1
--rw=write
--numjobs=1
--iodepth=128 \
--ioengine=libaio
--bs=4k --group_reporting
--name=oliver
--log_avg_msec=500 \
--write_bw_log=test-fio-rw
--write_lat_log=test-fio-rw
--write_iops_log=test-fio-rw
--size=100G --runtime=180
