Can you please explain this calculation in more detail? 

You get 10MB /1.5s = 6.7M/s ? But you said you load 40MB in 11s, what I 
would say is 3.6 MB/s. Please note that you should not substract IO time 
from the total loading time, as CPU should be working in parallel with the 
DMA, otherwise you are doing something _very_ wrong. 

Anyway, either 7MB/s, or 3.6 MB/s, this is just awfully slow. A 40xCDROM has 
transfer rate of 6MB/s. You say you are parsing data at that rate? Those are 
certainly not some impressive numbers. :(
