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
