Hi,
I am using qemu-system-arm for ARM Realview PBX-A9 board. I feel that the
performance (read/write) from the SdCard is slower than the case in which I
was mounting my rootfs through NFS. The size of my rootfs is around 3 GB. I
am making my SdCard image using qemu-img command and formatting it with ext3
filesystem. Is this a common phenomenon with everyone? Or am I doing
something wrong in the case of SdCard ?
Thanks in advance.

I've seen very slow sdcard performance too; it's on my todo list
to try to investigate but hasn't made it to the top yet.
