This is the same as reported last time.

Then I did similar test under Windows with libftdi-0.19 (with
Liminary's FTDI driver
and libusb-win32 filter driver). The speed is faster than under Linux. Kind of
interesting. I will try the ftd2xx Windows build later.

Do you have a Amontec JTAGkey-2 (High-speed USB 2.0) ?
If yes, please do the same comparaison with libusb and d2xx on Linux and
windows, and with the Amontec JTAGkey D2XX device driver package WHQL
certified .
Regards,
Laurent
