    File handling very slow and laggy Windows 7 and NAS (or Windows-Server)


    Three Windows 7 64bit and to WinXP 32bit workstations connected with TurboNAS or Windows Server ( we tried both..no difference)
    several issues:
    1) Data transferrate is just fine 30-50MB/s okay no complaints
    2) Windows 7 explorer very laggy .. right clicking on large TIFF files concerns 5 to 10 seconds delay on to property windows open
    ..... !!! very different with WIN XP no delay property windows opens up immediately
    3) Windows 7 Explorer refreshes every second !!!!! always never stops refreshing... collecting hundred of megabytes of data
    please see the attached screenshot
    ......!!! not at all with Win XP
    4) "open" and "save as" within Photoshop on Windows 7 is up to 10 times slower compared with Win XP but not the saving process itself ** its just the everlasting waiting for dialogue boxes.

    one more remarable issue:if you try to open a large image in Photoshop, in taskmanager the explorer.exe proccess grows until 400-1800MB a just in the moment it shrinks back to even zero Photoshop really starts loading !!!!!!!!!!!!!!!!!!!!!!!!!!!


    What I did:
    disable search
    disable 128-bit encryption
    netsh interface tcp set global autotuning=disabled
    disable Remote Differential Compression


    NONE OF THIS PROBLEMS OCCURE WITH Win XP ..why?




    any ideas what's wrong


    kind regards manfred
