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>`)

温馨提示
下载硬盘专家后,点击释放C盘系统空间,就可以节省出很多空间,win10系统一般节省出20G都是正常的,因为win10在很多地方都恶意占用磁盘空间,比如一些大型的垃圾,都没有及时清理,就算你使用杀毒软件里面的垃圾清理,也无法清理掉,其实每个杀毒软件或者清理软件所清理的内容都是不一样的,通常都提前知道了常用软件的哪些位置是垃圾,然后通过程序去清理,这种清理是不彻底的,会遗留很多垃圾,就好比不同的清洁工,有的只会清理客厅,有的只清理房间,还有整栋楼很多地方都没清理到位,其实都是垃圾,是需要清理掉的,尤其是系统长期使用后,垃圾更多!这个清理功能只清理垃圾,不会删除任何用户和系统相关的文件,我就是觉得清理垃圾太麻烦,所以制造了这么一个软件来帮我更愉快的使用win系统。官方下载地址:http://www.lccee.com/content-273-1.html
