Memory and File System

Accelerate DLL Unloading
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurr entVersionExplorerAlwaysUnloadDLL]
"(Default)"="1"

Anytime a process is ended this will force windows to try and unload any DLL files associated with the now closed application. This can and probably will have a negative affect on performance if you reopen applications not too long after closing them. If you have buttloads of RAM, don't do this one! It Free's up used RAM that most of us really do want.

Clearing PageFile on Shutdown
This one actually HURTS performance since it slows down your shutdown process since it has to delete your entire pagefile which in my case is over 1Gb! They say that it speeds your boot time up, which it may...

Disable Paging Executive
DisablePagingExecutive registry key is set to 1 which means Drivers and the kernel must remain in physical memory. The default is 0 which allows this data to be cached to disk sometimes. Forcing all of this information to stay in your RAM is a good idea, but can be bad for the people with 128Mb of RAM.

The best source of information I have found on this can be found here.

Faster Shutdown
Wait to kills both apps and services both have been lowered to 2 1000. This one really will help you shutdown noticeably faster most of the time.

FIle Allocation Size
ConfigFileAllocSize was set to 512
This one proves that the writer of this application reads my guides Unfortunately he included a tweak I had misspelled the f was supposed to be a t.... It is Contiguous File allocation size Unfortunately a user by the name of axmax proved me wrong on this tweak. It's ONLY a win9x tweak MS doc for 9x. I cannot find anything about this for NT bases OS's nor is there a default value for this key. I'm VERY sorry about this one everybody, it's my fault that a bad tweak was included in this app.

Optimize Prefetch
This changes the EnablePrefetcher key to a value of 3 which caches both boot process and applications. On systems with low amounts of RAM you will NOT want to use this tweak.

Increase NTFS Performance
NTFSDisableLastAccessUpdate is a very nice tweak to do. They could have included NtfsDisable8dot3NameCreation but I believe they decided to leave this one out since it has caused some issues with some software.

IO Page Lock Limit
this sets the IoPageLockLimit key
Specifies the maximum number of bytes that can be locked for I/O operations. According to this document the settings are slightly off by this application. If you have < 64Mb it should be RAM size - 7Mb. For 64Mb-500Mb it should be RAM size - 16Mb. For 512Mb and greater it should be RAM size minus 64Mb. This is a tweak that I did not include in my tweaking guide, but I will in the next revision due to so many people not using this properly.

Clear Prefetch Folder
This opens a little DOS box that deletes all the contents of windows/prefetch. There's been a bit of debate on the affects of doing this, but I personally clear it from time to time which means that I agree with the usage of this tweak.

Defrag Boot Files
This uses defrag.exe -b

Disable Zip
Unregisters zipfldr.dll which stops the windows built in zip program.

Ultra Fast Booting
This setting is what truly makes this program worth downloading! I haven't quite figured out exactly what it does yet, but even on my already tweaked out systems it improved my boot speed! I know it does something additional with defrag.exe that I haven't found any documentation on yet and it does a bit more than just defragmenting. I honestly don't know yet.... Hopefully I can learn more about this as I continue to investigate.
