»Solution to slow file and folder browsing (LAN Network)«


I found a solution for something that has been bugging me for a while:
Browsing files and folders on my network (Ethernet) was pretty slow, while transferring large files was fast.

I have a local area network (LAN) with gigabit ethernet cards and the transfers are fast (e.g. transferring 100MB file). However, browsing folders (= listing files) was slow.

Not really slow like 30 seconds per folder (that can only happen with some strange bugs or incompatibilities) but 1-2 seconds per folder. Even re-reading folders that just have been read caused this 1-2 seconds delay.

Although 1-2 seconds per folder might not sound much, it adds up when you run a file search or open a program that reads folders with many files (e.g. email programs, picture viewers).

The solution:
• open regedt32.exe (or regedit.exe) to edit the registry
• open the branch HKEY_LOCAL_MACHINE\ System\ CurrentControlSet\ Services\ LanmanServer\ Parameters
• if there is no parameter called "SizReqBuf" then create it (DWORD)
• Set it as decimal 14596 or higher

Another thing you might want to do is to DISABLE the "Last accessed timestamp". This flag is changed whenever you merely open a file (even when you don't change it). Not to confuse with the "Last modified timestamp" (= when was the last time you WROTE to the file).

Do the following:
• open regedt32.exe (or regedit.exe)
• create/change HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ FileSystem
• Set/create "NtfsDisableLastAccessUpdate" (REG_DWORD)
• Set to 1


This has no effect on "last modified" time stamp, of course.
