[Solved] High Memory Usage by Metafile on Windows 2008 R2

Dear All,

Have you seen such type of task manager parameters in any of your server? if please read the below scenario

You can see the memory utilized is 98% and when I went to processes tab I saw as below

But when I tried to sum all processes memory it was not going beyond 50 % so where the memory is getting utilized?

Installed RAMMap.exe of sysinternals and checked

After reading lot on various blogs I came to know metafile is

” Metafile is part of the system cache and consists of NTFS metadata. NTFS metadata includes the MFT as well as the other various NTFS metadata files… In the MFT each file attribute record takes 1KB and each file has at least one attribute record. Add to this the other NTFS metadata files and you can see why the Metafile category can grow quite large on servers with lots of files ”

checked for file type wise disk space utilization and 98 % of E: contains around 228 GB of JPG files

So searched further for ” how to clean / reduce METAfIle size ” and most of blogs where suggesting to install Dynamic Cache Service so tried that also but the service doesn’t work with windows 2008 r2 Web edition.

Now what to do ?

After lots of efforts ….. got the solution

As I have clicked on “Empty System Working Set” the memory utilization started reducing from 98% to………. 48 % J
