IOmeter & PCMark 8

IOmeter

IOMeter is an I/O subsystem measurement and characterization tool for single and clustered systems. It is used as a benchmark and troubleshooting tool and is easily configured to replicate the behavior of many popular applications. One commonly quoted measurement provided by the tool is IOPS.

IOMeter allows the configuration of disk parameters such as the ‘Maximum Disk Size’, ‘Starting Disk Sector’ and ‘# of Outstanding I/Os’. This allows a user to configure a test file upon which the ‘Access Specifications’ configure the I/O types to the file. Configurable items within the Access Specifications are Transfer Request Size, Percent Random/Sequential distribution, Percent Read/Write Distribution, Aligned I/O’s, Reply Size, and TCP/IP status among others.

Sequential Performance

The IOmeter performance tests are all run with four workers, one for each CPU core. The sequential performance tests are run with 128 Kilobyte packets at 100% sequential distribution. Each test is run for 20 minutes and only the last result is shown. This is a great way to show continuous performance rather than an average result.

Random 4K Performance

The random performance tests are also run with four workers and for a duration of 20 minutes. The difference is the workload which in this case is set up with 4 Kilobyte packages and 100% random distribution.

PCMark 8

PCMark 8 Storage benchmark is used test the performance of SSDs, HDDs, and hybrid drives with traces recorded from Adobe Creative Suite, Microsoft Office and a selection of popular games. You can test any recognized storage device, including local external drives. Unlike synthetic storage tests, the PCMark 8 Storage benchmark highlights real-world performance differences between storage devices.
