如何将 Fio 配置为更准确的 IOP 结果

772

我正在使用 fio 来测试我的服务器可以提供多少 iops。我的 conf 文件说要写一个 20GB 的文件并读取它。结果显示 iops=27291。但测试只持续了10秒。例如，我想知道测试是否持续 2 小时，我会得到关于我的服务器 IOP 的更准确的结果。

# cat fio/fio-readwrite-20g.fio 
[global]
ioengine=posixaio
rw=readwrite
size=20g
directory=/home/ustore/fio
thread=10
write_bw_log=fio-test
write_iops_log=fio-test
write_lat_log=fio-test

[fio-readwrite-20g]

   runtime=int
          Terminate processing after the specified number of seconds.

   time_based
          If  given, run for the specified runtime duration even if the files 
          are completely read or written. The same workload will
          be repeated as many times as runtime allows.
