 Performance Utilities

Our Top Picks:   

AutoPilot Size: 400K Shareware: $49.95
AutoPilot P/SA automatically and transparently detects and eliminates system bottlenecks. These bottlenecks occur because of overloads or problems occurring in any of the following system component areas: system bus contention; disk I/O contention; network I/O contention; memory subsystem problems; poor cache utilization and affinity cache thrashing; spin lock and semaphore contention; unnecessary context switching; page thrashing.

Cacheset Size: 14K Freeware
CacheSet is an applet that allows you to manipulate the working-set parameters of the system file cache. In addition to providing you the ability to control the minimum and maximum working set sizes, it also allows you to reset the Cache's working set, forcing it to grow as necessary from a minimal starting point. Also unlike CacheMan, changes made with CacheSet have an immediate effect on the size of the Cache. Full source code is included. You must be logged in with Administrator privileges to use this applet.

Contig Size: 20K Freeware
Contig is a single-file defragmenter that attempts to make files contiguous on disk. Its perfect for quickly optimizing files that are continuously becoming fragmented, or that you want to ensure are in as few fragments as possible.

Frob v1.6a Size: 16K Freeware
One of the most annoying characteristics of NT/Win2k is its lack of support for tuning various system performance settings such as the foreground and background process quanta (a quantum is the time-slice, or length of time a thread will run without being pulled off the CPU for another thread to run). Well, here's a little applet that will let you "frob" the quanta to your liking. The new quanta will immediately be applied to every process in the system and will also affect new processes that are created. 

MemTurbo II Size: 750k Shareware: $30.00
MemTurbo increases your system performance by making more RAM available for your applications and the operating system.  It also defragments your physical RAM, increasing the efficiency of your CPU and Motherboard caches. MemTurbo also recovers memory leaks from poorly behaved applications and flushes unused libraries and DLLs temporarily out to disk, making more room for your favorite games or applications.

Mamba Size: 12.1 Mb Freeware
Mamba provides a Web-based dashboard for monitoring the health and availability of your entire Windows NT/2000 environment, including hardware and key applications such as Exchange Server, IIS Web Server, and SQL Server. Accessible from any browser, Mamba provides a quick, clear, and comprehensive overview of all key Windows NT/2000 performance metrics from system capacity to availability to performance, enabling quick problem determination and resolution. Mamba provides administrators with the clear, real-time data they need to react quickly to existing and emerging performance issues.

PageDefrag Size: 34K Freeware
One of the limitations of the Windows NT defragmentation interface is that it is not possible to defragment files that are open for exclusive access. Thus, standard defragmentation programs can neither show you how fragmented your paging files or Registry hives are, nor defragment them. PageDefrag uses advanced techniques to provide you what commercial defragmenters cannot: the ability for you to see how fragmented your paging files and Registry hives are, and to defragment them.

Passmark PerformanceTest Size: 856K Shareware: $16.00
An award winning PC hardware benchmark utility that allows everybody to quickly assess the performance of their computer and compare it to a number of standard 'baseline' computer systems. PerformanceTest's small foot print means you can take it with you when you go out shopping for PC and benchmark before your buy. The other major advantage is the built in baseline results that enable an objective comparison to be made between computer systems. The benchmark results are presented as easy to read bar charts and timing is done using high resolution timers. Rated 5 starts by ZDNet

If you are looking for additional sources of Utilities, try these sites:

Beverly Hills Software
This sites been around a long time, and they do a great job. Software is rated, and easy to find, but some days the site seems a little slow.  
Great site, although a bit tough to navigate. Literally hundreds of programs are available.


SunBelt Software
Sunbelt Software is the world's first and largest provider of 'Best of Breed' NT Utilities. You get mainframe quality tech support, and the best tools all from one source. They also have a few great mailing lists, an online Tech "University", and a tech Glossary.

Well organized, and fast. Gotta love a page that gives a "Five Cow" rating for software. However, you may have to wade through a ton of end user software before you get to applications that you may actually find useful. NT Shareware
One of our favorite sites. All of software is well organized, lists license status, price, size, download time, etc., and the site is searchable.
