With this parameter, both threads share a single interlocked offset so that the threads cooperatively issue a single sequential pattern of access to the target file. This allows no one point in the file to be operated on more than once.

How is IOPS measured?

IOPS is often measured with an open source network testing tool called an Iometer. An Iometer determines peak IOPS under differing read/write conditions. Measuring both IOPS and latency can help a network administrator predict how much load a network can handle without performance being negatively affected.

How is hard drive performance measured?

To test the speed of your hard disk:

  1. Open Disks from the Activities overview.
  2. Choose the disk from the list in the left pane.
  3. Click the menu button and select Benchmark disk… from the menu.
  4. Click Start Benchmark… and adjust the Transfer Rate and Access Time parameters as desired.

How does Windows calculate disk IOPS?

Run a Perfmon using Physical Disk:Reads/sec, Physical Disk:Writes/sec, Physical Disk:Write Disk Queue. A high disk queue means the OS is waiting for time to write to the disk. The writes/reads will tell you what your IOPS are currently running.

What is an IOPS test?

August 2016) (Learn how and when to remove this template message) Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN).

How many IOPS does a VM need?

50-100 IOPS per VM can be a good target for VMs which will be usable, not lagging. This will keep your users happy enough, instead of pulling their hair.
