Dear all,


We run Android BSP on MX6Quad SABRE-SDB board.

We noticed that memory reading speed was different between Android4 .4.2 and Android4 .4.3.


<Measurement result>
* Android4.4.2
    eMMC Seq.Read=47.49MB/s,   SD Seq Read=22.69MB/s

* Android4.4.3
    eMMC Seq.Read=35.38MB/s,   SD Seq Read=17.92MB/s


Would you tell me the factor of the difference in this speed?


May I have any advice?


Best Regards,
