MFT (Master File Table) manipulations to improve disk performance

MFT stands for Master File Table. Typically in Windows XP , if you are
using NTFS ( I would recommend it if you don't) then by default,NTFS would
reserve 12.5% of your free diskspace for MFT. MFT fragmentation could also
cause a significant slow down. Let me discuss size first. Now if you have
installed tons of different programs on your hard disk (or intend to do
so), MFT utilization is going to be high. Under such situation, it may be
beneficial to increase this percentage to say 25%. If you want to do this,
here is the the trick. Open Registry by going to START-RUN and entering
REGEDIT and Navigate to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem. In right
pane, Add one more key by the name "NtfsMftZoneReservation" with the
REG_DWORD value of 2. DWORD value of 1 is interpreted as 12.5% ,2 as 25%
and so on.
