Question

Greetz fellows!

I’m looking for a way to log actions of a CLI script without losing time. I did some benchmarks and I figured out that by echoing someting after each action, the script will be nearly 2x slower and by appending actions to a log file it’ll be 17x times slower.

So, anyone has a solution?

Answer 1

If you are using CLI, I guess you can test with this:

YOUR_SCRIPT.php > /tmp/log.txt &

Inside YOUR_SCRIPT.php

<?
  /* some action */
  echo date('r').some_action_1()."\n";   <-- this is bad  # REMARK 1
  echo date('r').some_action_2()."\n";

  echo date('r'), some_action_1(), "\n"; <-- this is nice # REMARK 2
  echo date('r'), some_action_2(), "\n";
?>

And monitor using

tail -f /tmp/log.txt

The reason REMARK 1 slow is because function execute first, while REMAKR 2 does not (output first)
