I read about this trick the other day over Internet. Open Registry by going
to START-RUN and typing REGEDIT. Navigate to
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management\IoPageLockLimit. Depending upon how much RAM you have, you can
increase your diskcache size by entering a higher value in IoPageLockLimit.
Typically your computer won't come optimized for diskcache and you can set
to a value which works best for you by trial and error.Rule of thumb is to
have a ratio of 1 or 2 for every 64K chuck. But try out various different
values as each case would be a little different
