What's New? =========== ## DISKSPD ## DISKSPD 2.0.21a 9/21/2018 * Added support for memory mapped I/O: * New `-Sm` option to enable memory mapped I/O * New `-N<vni>` option to specify flush options for memory mapped I/O * Added support for providing Event Tracing for Windows (ETW) events * Included a Windows Performance Recorder (WPR) profile to enable ETW tracing * Added system information to the ResultParser output DISKSPD 2.0.20a 2/28/2018 * Changes that may require rebaselining of results: * New random number generator that may show an observable decreased cost * Switched to 512-byte aligned buffers with the `-Z` option to increase performance * New `-O` option for specifying the number of outstanding IO requests per thread * New `-Zr` option for per-IO randomization of write buffer content * XML: Adds a new `<ThreadTarget>` element to support target weighting schemes * Enhanced statistics captured from IOPS data * Added support for validating XML profiles using an in-built XSD * Added support for handling RAW volumes * Updated CPU statistics to work on > 64-core systems * Updated calculation and accuracy of CPU statistics * Re-enable support for ETW statistics DISKSPD 2.0.18a 5/31/2016 * update `/?` example to use `-Sh` v. deprecated `-h` * fix operation on volumes on GPT partitioned media (<driveletter>:) * fix IO priority hint to proper stack alignment (if not 8 byte, will fail) * use iB notation to clarify that text result output is in 2^n units (KiB/MiB/GiB) DISKSPD 2.0.17a 5/01/2016 * `-S` is expanded to control write-through independent of OS/software cache. Among other things, this allows buffered write-through to be specified (`-Sbw`). * XML: adds a new `<WriteThrough>` element to specify write-through * XML: `<DisableAllCache>` is no longer emitted (still parsed, though), in favor or `<WriteThrough>` and `<DisableOSCache>` * Text output: OS/software cache and write-through state are now documented separately (adjacent lines) * Latency histogram now reports to 9-nines (one part in one billion) in both text and XML output * Error message added for failure to open write-content source file (`-Z<size>,<file>`) Source Code =========== The source code for DiskSpd is hosted on GitHub at: <https://github.com/Microsoft/diskspd> Any issues with DiskSpd can be reported using the following link: <https://github.com/Microsoft/diskspd/issues>
