This is the command line: qemu-system-armw -M versatilepb -kernel ..\BaseQemu\zImage -hda ..\BaseQemu\rootfs.squashfs -hdb ..\BaseQemu\flash.ext3 -append "root=/dev/sda r" -net tap,ifname=TAP,script=no -net nic
I talked with the developer here and it seems that the bad speed is mainly due to latency. We are investigating also on our side because we use a "special" environment: in fact, we use VisualGDB to debug from Visual studio into qemu. It seems that VisualGDB's ssh client has poor performances but I don't know yet where the latency come from.

Can you share the QEMU command-line and the benchmark used to measure this result? Stefan
