The most of card readers today are USB 2.0, is your device
USB 2.0? Also what storage card you are talking about? Are
the drivers behind the USB and storage optimized and are fully
utilizing the h/w capabilities like DMA etc?
ActiveSync protocol itself is not that slow compared to some
others, however the underlaying interface/drivers may be slow.
Also note that AS will be converting certain file types
while copying to device ...

hi,.
are there known performance issue with activesync over usb?
i run a oem device that has activesync using usb function. if i copy
files to the device memory card it is much slower compare to
remove the memory card to external card reader.
is this "normal"? what i'm asking, is if there is idea for me to
start looking for performance problems? will activesync with
optimized drivers ever have same performance as external
card reader?
maybe the overhead of activesync protocol, or bad implementation
of active sync protocol is bottleneck? (even if i had optimized drivers)
this is ce5 platform.
would ce6 make difference?
