Yes, I believe the micro SD card IO bandwitch is mainly responsible for the network limitation,
but I am very surprised as I purchased a quality (supposed to be) micro SD card : MicroSDHC SanDisk Extreme Plus 32 Go up to 95 Mo/s, Classe 10, U3
So my first issue to solve is understand why I get so poor IO with this micro SD card, perhaps using "hdparm -t /dev/mmcblkp0" is not the appropriate tool (?)
Another point is the CPU : I should try another transfer application than ssh/sshd for big files to avoid the CPU crypting/decrypting burden, or perhaps this one could get accelerated with the sunxi-ss module ?
My main concern is the micro SD card, I just cannot accept such poor reading/writing for what I paid.
Any suggestions are welcomed.
EDIT : I am all the more surprised of the micro SD card performance as the boot process is really fast (a few seconds), in accordance with what I expected from this micro SD card.
