Sluggish
file
transfer causes major problems in Windows
Vista as compare to Windows XP, simply because Vista is
design for consistent
high
speed and low speed connection, but almost
unsuitable for home office environment with moderate speed
connection!
Don't get me wrong here, Vista performs very fast on
advanced networking environment, but introduced too much
overhead in normal home office environment, you just need to
disable some settings to reduce the overhead, all is done in
2 simple steps.
Unless you equipped with advanced PC and networking devices,
your can expect performance dropped by 20~50% during files
transfer as compare to XP, so lets' find the reasons and
solve the problems now:
1. Remote Differential Compression - This protocol
calculates, compress and only
transfer
files with updated version, hence files
synchronization works extremely well on lower bandwidth
networking, but slows down normal networking with extra
overheads in compression. Using a
faster
processor can improve Remote Differential
Compression as Vista trade processing power over networking
bandwidth by compressing the data before transferring it.
You should always disable this features on older and slower
computer, because you have more bandwidth than processing
power!
2. TCP Auto Tuning Features - This feature maximize your
gigabit networking by automatic and constantly adjusting
itself to adapt to the maximum bandwidth available by your
hardware; It performs very well on high bandwidth
environment, but not very good on low bandwidth networking
due to extra overheads of detection, and also went bad when
using unsupported hardware such as firewall or routers.
You can disable these features to speed up Vista for another
20% to 30% faster, just remember to enable them if you
upgraded your computer or networking in the future.
To disable Remote Differential Compression, go to Control
Panel -> Programs -> Turn Windows Features On or Off,
uncheck Remote Differential Compression and then press OK
button.
To disable TCP Auto tuning, press Windows key and type "CMD.
exe" then press Ctrl+Shift+Enter to run as Administrator,
then type " netsh interface tcp set global autotuning=disabled",
now type "exit" to return to Windows.
If you decided to turn on this feature after upgraded your
hardware, do the same but type " netsh interface tcp set
global autotuning=normal" to turn on the TCP auto tuning
feature.
You can try to send some files now, you should notice more
improvement on your file transmission, your file is send
across network or disk much faster!
