dilemma what to use c++ or script for demon process

Hello all
i need to implement demon that needs to extract data from db load the data to memory and according to this data
to perform actions like sending emails or write/update files this action needs to be preformed each 30 min's
now i really don't know what to decide or to compile c++ program that will to the task or to use scripts and misc Linux tools ( sed /awk )
what will be the fastest way to do this? to save cpu and memory .
the dilemma is about marinating this process if its script it does not need compilations and i can just drop it into any machine linux/unix
but if its native its more harder .
what do you think?
