  On My board i have RAM of 8 MB and swapping is disabled.when my 
 system comes up i download binaries (Linux Kernel + Other Application
 Binaries) from flash on the board to the RAM and start processing.

  As i think if 

 a) i allow page caching then there is going to be 2 copies of
  data in my system and i want to avoid it.

 b) Always  my process pages are going to be in RAM and there would be
    no page fault(Unless application have bugs b'se swapping is 
    disabled).
  
   
Regards
Anil
