in reply to Performance In Perl

Hi Mano_Man

I assume it is mostly a design decision:

  • do you need the info in $toPrint later?
  • is it a benefit to use the say/print at only one place?
  • do you want to give error-messages as soon as possible?
In my experience, the performance-differences are neglectable (but your use-case might be different).

However I have experienced an issue in the past with redirecting the output to a file, using the > in a windows batch file: IIRC it didn't work when printing a text that was too long - it seemed that the data was sent out by print was much faster than the writing to the file. Unfortunately, I can't find the old script where this happened... but it might a thing you want to check/consider.

HTH, Rata
