Vista to XP used to work fine, but now that all three machines are Vista,
local network performance is terrible. When transferring large files from
machine to machine, the network performance graph consists of spikes from 0
to 5-60%, but there are many seconds between the spikes! Sometimes there is
no transfer for 5-20 seconds. There is effectively no CPU utilization either
during the spike or during the time of no activity. There is basically no
drive access during the dead time.
This symptom is NOT like the smooth cap that is seen due to concurrent audio
playback.
I have tried:
Uncheck QOS
Uncheck IPv6
Autotuninglevel=disable
All machines are connected through a gigabit switch with support for jumbo
frames (but jumbo frames are not turned on in the adapter configs.)
Why the long pauses and inconsistent spikes? Any input is appreciated.
