Still looking----buffer size reg. tweak

Post by Sag2734 »

Is there a place in the registry where I can change or increase the HardDisk read ahead buffer-size

BOOST HARD DISK READ AHEAD CACHE:
The best part is that you can also increase the "ReadAheadThreshold" Binary [hex] Value (which applies to ALL drives installed in your Windows 98/ME system, NOT available on Windows 95/OSR1/OSR2!) under this Registry key (as displayed in a REG file):

-----Begin cut & paste here-----
REGEDIT4

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\control\FileSystem]
"ReadAheadThreshold"=hex:00,00,00,0f
------End cut & paste here------

In this case the read ahead threshold is set to 1.87 MB (1920 KB).
The beauty is that Windows uses this memory dynamically to read ahead, only when opening files/folders, returning it back to the system afterwards.

As far as I'm aware these are the maximum values allowed by Windows 9x for "ReadAheadThreshold", "NameCache" and "PathCache" (save this as a REG file):


-----Begin cut & paste here-----
REGEDIT4

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem]
"ReadAheadThreshold"=hex:00,00,00,ff
"NameCache"=hex:00,ff,00,00
"PathCache"=hex:ff,00,00,00

[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\FS Templates\Maximum Performance]
@="Maximum Performance"
"NameCache"=hex:00,ff,00,00
"PathCache"=hex:ff,00,00,00
------End cut & paste here------
Find this and much more here. :)
