check iops read/write with fio on centos 6.x

###check iops read/write with fio on centos 6.x

cd /root
yum install -y make gcc libaio-devel || ( apt-get update && apt-get install -y make gcc libaio-dev  </dev/null )
wget https://github.com/Crowd9/Benchmark/raw/master/fio-2.0.9.tar.gz ; tar xf fio*
cd fio*
make

Random read/write performance

If you simply want a way to compare different provider's disk performance, then this is the test I suggest. Run the following command:
   
./fio --randrepeat=1 --ioengine=libaio --direct=1 --gtod_reduce=1 --name=test --filename=test --bs=4k --iodepth=64 --size=4G --readwrite=randrw --rwmixread=75
   
This will create a 4 GB file, and perform 4KB reads and writes using a 75%/25% (ie 3 reads are performed for every 1 write) split within the file, with 64 operations running at a time. The 3:1 ratio is a rough approximation of your typical database.

FIO will now tick along printing a summary as it goes, that looks like this:
  Jobs: 1 (f=1): [m] [6.5% done] [39613K/13099K /s] [9903 /3274  iops] [eta 01m:12s]
