redirect - In general, does redirecting outputs to /dev/null enhance performance? -


suppose have program prints large number of messages stdout, takes time. wonder whether redirecting stdout /dev/null (so see no messages in screen) can make program terminate faster?

[edit] tries small examples. redirecting stdout /dev/null make program terminate earlier.

yes. outputting screen requires lot of painting. outputting file faster, because it's running @ disc speed. outputting /dev/null faster yet, because output goes nowhere.
