A QOS aware application can request priority bandwidth but few do. Even if this occurs there will be no bandwidth reduction unless it is actively using it. Any unused bandwidth will be available to other applications. All this tip does is set the maximum bandwidth that "can" be reserved, not the bandwidth that is reserved. This setting will have no effect except on a large network in which case network wide policies will usually override any local settings.

]]> Comment on IRQ Priority Boost by Larry Miller http://www.windowsmonitor.net/irq-priority-boost.html#comment-47 Larry Miller Tue, 13 May 2008 18:20:07 +0000 http://www.windowsmonitor.net/irq-priority-boost/#comment-47 THIS IS A MYTH This tweak does absolutely nothing. There are many problems with this, not the least of which is the choice of IRQ8. The CMOS is a hardware device that holds the systems boot configuration and system clock. After startup XP has little reason to access either. The real time clock has no performance implications. It is hard to imagine how increasing the priority of this IRQ would improve performance. The original author of this tweak is unknown but it has been passed from one uninformed web site to another for a long time. Larry Miller Microsoft MCSA CompTIA Network+, A+ THIS IS A MYTH

]]> Comment on Unload.dll’s to Free Memory by Larry Miller http://www.windowsmonitor.net/unloaddlls-to-free-memory.html#comment-46 Larry Miller Tue, 13 May 2008 12:08:01 +0000 http://www.windowsmonitor.net/unloaddlls-to-free-memory/#comment-46 BAD ADVICE Windows does not immediately unload DLL's for performance reasons. And it is not only DLL's that are retained in memory, this is done with program code as well. To do so would be a violation of an important Windows design principle. This is to always find some use for as much memory as possible, even if it is of trivial value. Any use of memory s better than no use at all. Free memory is the absolute ultimate in wasted memory. Caching has had a long and distinguished history in computer systems and it is highly developed in XP. Windows has a complex and efficient system for reclaiming the memory used by caching when it is needed. Until this occurs there is no need to unload a DLL or otherwise free memory. Reloading a prematurely unloaded DLL will impair performance. Windows designers know more about memory management than you do. Let caching work for you and improve performance. Do not follow this well meaning but uninformed advice. Larry Miler Microsoft MCSA CompTIA Network+, A+ BAD ADVICE
