You are right, the low performance of displaying *.rtf file to RichTextBox is related to the contents of *.rtf file.And I found that RichTextBox of C# loads *.rtf very slow only when *.rtf has a particular data pattern.The following procedure is to re-create this performance issue.

However, please note : If you use MSAccess2003, create a new form and add a RichTextBox control on it, and then fire the LoadFile derived function from the so-created OLE object, you'll see the very same performance as WordPad (for me a few seconds to load 2mo compared to 330sec for the VB control).

The SysMain service and the Memory Compression process are used to improve computer performance. But sometimes it happens that the memory compression process starts to heavily load the CPU or hard drive of the computer (up to 100%, this can be seen in the Task Manager), or takes up too much RAM resources. Of course, the computer starts to work slow or hangs up.

These tips can help you get to rid of the high load of the computer by the Compressed Memory process. However, this disables the underlying Windows performance optimization features, which may adversely affect the overall performance of your device.

For each major current network and client system version that becomes generally available Revelation Software will conduct intensive benchmark testing with our OpenInsight, Advanced Revelation and Network products for functionality, data integrity and performance. The configurations listed within this matrix are supported environments. Revelation Software is no longer conducting benchmark tests for product versions below OpenInsight 9.x and Advanced Revelation 3.12.

The UD 5.0.0.5 contains bug fixes, an improved UD manager, and a client installer which exposes more UD5 features. A bug which caused a client to hang upon repeated toggling of the resize service is fixed. Version 5.0.0.5 supports passing REVPARAM information via a volume pointer or call to ATTACH_TABLE. Some core system routines including RTP57, RTP49, FIX_LH and RTI_LH_INFO are updated. The UD client installer replaces the REVBOOT file and installs the UD_MANAGER and supporting components into your OpenInsight. With these changes, the UD manager displays lock and session details in a format of MACHINE*USER*PROCESSID. This format lets you determine lock holders in a terminal server or O4W environment. The UD manager window ( MANAGE_REVLH_SERVER ) provides access to sub windows displaying statistics, statistics history, size lock and remake table information. It also resolves a long-standing issue with corrupted table header counts and sizes, and includes new options to disable or re-enable automatic resizing of tables.

By default OpenInsight 8.x includes the All Networks Driver 1.5 and 2.1 drivers. Both drivers can be utilized with or without the LinearHash service. For performance and reliability reasons we recommend all multi-user systems run the Universal Driver 3.0+ which includes the LinearHash service. All other multi-user configurations are unsupported and no longer tested.

Crystal DiskMark is a compact testing software for testing the writing and reading rate of large- and small-size files. In the continuous reading and writing performance test which utilized it as the chief testing tool, PQI SSD S527 256GB exhibited the fastest writing rate of 167.4MB/s as well as the fastest reading rate of 235.3MB/s. When the file size was switched to 512KB, most of the SSDs slowed down just slightly in reading, while the writing rate average dropped by nearly 50 percent. In tests with small-size file, the situation was similar to the former ATTO test.

The SSD products exhibited really impressive performance in writing and reading efficiency in the PCMARK 05 test. Unlike the hard disks which require motor running and the reading head to move, the SSD products require a searching time near 0, which ensures the improvement in input/output per second (IOPS), and sequentially in the random reading efficiency reflected in the performance of SSD products. As the HDD score in PCMark05 test is a overall measurement, it can be concluded that the products with best overall performances are A-Data S592 and OCZ Vertex which matches each other, and the following PQI SSD S527 also performs well and features high storage capacity, while the higher temperature than other SSD products is to be noted.

By 2004, it had become obvious to the Windows team at Microsoft that they were losing sight of what needed to be done to complete the next version of Windows and ship it to customers. Internally, some Microsoft employees were describing the Longhorn project as "another Cairo" or "Cairo.NET", referring to the Cairo development project that the company embarked on through the first half of the 1990s, which never resulted in a shipping operating system (though nearly all the technologies developed in that time did end up in Windows 95 and Windows NT[16]). Microsoft was shocked in 2005 by Apple's release of Mac OS X Tiger. It offered only a limited subset of features planned for Longhorn, in particular fast file searching and integrated graphics and sound processing, but appeared to have impressive reliability and performance compared to contemporary Longhorn builds.[17] Most Longhorn builds had major Windows Explorer system leaks which prevented the OS from performing well, and added more confusion to the development teams in later builds with more and more code being developed which failed to reach stability.

After Longhorn was named Windows Vista in July 2005, an unprecedented beta-test program was started, involving hundreds of thousands of volunteers and companies. In September of that year, Microsoft started releasing regular Community Technology Previews (CTP) to beta testers from July 2005 to February 2006. The first of these was distributed at the 2005 Microsoft Professional Developers Conference, and was subsequently released to beta testers and Microsoft Developer Network subscribers. The builds that followed incorporated most of the planned features for the final product, as well as a number of changes to the user interface, based largely on feedback from beta testers. Windows Vista was deemed feature-complete with the release of the "February CTP", released on February 22, 2006, and much of the remainder of the work between that build and the final release of the product focused on stability, performance, application and driver compatibility, and documentation. Beta 2, released in late May, was the first build to be made available to the general public through Microsoft's Customer Preview Program. It was downloaded over 5 million times. Two release candidates followed in September and October, both of which were made available to a large number of users.[24]

Development of Windows Vista came to an end when Microsoft announced that it had been finalized on November 8, 2006, and was concluded by co-president of Windows development, Jim Allchin.[32] The RTM's build number had also jumped to 6000 to reflect Vista's internal version number, NT 6.0.[33] Jumping RTM build numbers is common practice among consumer-oriented Windows versions, like Windows 98 (build 1998), Windows 98 SE (build 2222), Windows Me (build 3000) or Windows XP (build 2600), as compared to the business-oriented versions like Windows 2000 (build 2195) or Server 2003 (build 3790). On November 16, 2006, Microsoft made the final build available to MSDN and Technet Plus subscribers.[34] A business-oriented Enterprise edition was made available to volume license customers on November 30, 2006.[35] Windows Vista was launched for general customer availability on January 30, 2007.[3]

Vista includes technologies such as ReadyBoost[59] and ReadyDrive, which employ fast flash memory (located on USB flash drives and hybrid hard disk drives) to improve system performance by caching commonly used programs and data. This manifests itself in improved battery life on notebook computers as well, since a hybrid drive can be spun down when not in use.[60] Another new technology called SuperFetch utilizes machine learning techniques to analyze usage patterns to allow Windows Vista to make intelligent decisions about what content should be present in system memory at any given time. It uses almost all the extra RAM as disk cache.[61] In conjunction with SuperFetch, an automatic built-in Windows Disk Defragmenter makes sure that those applications are strategically positioned on the hard disk where they can be loaded into memory very quickly with the least physical movement of the hard disk's read-write heads.[62]

As part of the redesign of the networking architecture, IPv6 has been fully incorporated into the operating system[63] and a number of performance improvements have been introduced, such as TCP window scaling.[64] Earlier versions of Windows typically needed third-party wireless networking software to work properly, but this is not the case with Vista, which includes more comprehensive wireless networking support.[65]

Whereas prior releases of Windows supported per-file encryption using Encrypting File System, the Enterprise and Ultimate editions of Vista include BitLocker Drive Encryption, which can protect entire volumes, notably the operating system volume. However, BitLocker requires approximately a 1.5-gigabyte partition to be permanently not encrypted and to contain system files for Windows to boot. In normal circumstances, the only time this partition is accessed is when the computer is booting, or when there is a Windows update that changes files in this area, which is a legitimate reason to access this section of the drive. The area can be a potential security issue, because a hexadecimal editor (such as dskprobe.exe), or malicious software running with administrator and/or kernel level privileges would be able to write to this "Ghost Partition" and allow a piece of malicious software to compromise the system, or disable the encryption. BitLocker can work in conjunction with a Trusted Platform Module (TPM) cryptoprocessor (version 1.2) embedded in a computer's motherboard, or with a USB key.[78] However, as with other full disk encryption technologies, BitLocker is vulnerable to a cold boot attack, especially where TPM is used as a key protector without a boot PIN being required too.[79] 2ff7e9595c
