The Memory and File System category is clearly the biggest category of them all.
In this category, you will find tweaks that alter the very way, Windows XP works with memory at.
ACCELERATE DLL UNLOADING
Recommended for benchmarking
This tweak affects the swiftness of Windows to unload cached DLLs from the
main memory. This tweak makes sure that
no DLL will clog up the RAM by uncaching them quicker. Might be a performance
gain in benchmarks, but might slow down
general
Windows usage by a small amount
CLEAR PAGEFILE ON SHUTDOWN No
recommendation
This tweak makes Windows clear the pagefile on shutdown. Will make shutdown
slower, but might make bootup and paging
a bit faster (marginally)
DISABLE PAGING EXECUTIVE
512MB RAM or more required
This tweak removes the pool of system files that Windows will force to be
paged. Instead, they will be loaded into the
RAM. This tweak will use a bit of memory, but will make Windows quicker and more
responsive.
FASTER SHUTDOWN
Recommended for everyone
This tweak alters the speed of Windows application/service shutdown times
from 20 seconds to 1, and will make
Windows shutdown around 5 times quicker.
FILE ALLOCATION SIZE TWEAK
Recommended for everyone
This tweak alters the size of the memory file allocation size. The effect
is not drastic, but most people see a
(slight) improvement in general responsivity.
OPTIMIZE PREFETCH
Recommended for everyone
This tweak optimizes the way, the Windows prefetcher works. The
prefetcher allocates short bits of applications and
DLL's and speeds up the process of application loading (especially larger
applications) by doing so
INCREASE NTFS PERFORMANCE
Recommended for NTFS users
This tweak removes the "Last Access Stamp" from all files. This improves
general disk performance by removing
massive bandwidth overhead.
IO PAGE LOCK LIMIT
Recommended for everyone
This tweak alters the size of the IO paging area in memory. The larger
RAM amount you have, the higher a limit
you can set. Improves general performance, especially when loading larger
applications.
CLEAR PREFETCH FOLDER
Recommended for everyone
This tweak cleans out the folder with all the prefetches, Windows has
allocated. This is recommended to be done
every now and then (for instance, every week) to improve the general Windows
performance.
In version 1.5, this tweak has been bug fixed
DEFRAG BOOT FILES
Recommended for everyone
This function quickly assembles the bootfiles and stacks them together.
Speeds up boot performance.
DISABLE ZIP FOLDERS
Recommended for people with a 3rd party archiving tool
This function uninstalls the builtin ZIP capability of Windows. This
frees up resources, but if you want to open
ZIP-files afterwards, you will need a 3rd party application, like WinZip or
WinRAR.
ULTRA-FAST BOOTING
Recommended for everyone
This is a multi-stage tweak. First, it moves the bootfile to the edge of
the drive, after which it defrags the
system drive. Can reduce Windows boot time substantially, sometimes more than
300%
