linux - why the perl compiled code takes more memory? -

-

following sample code file name while.pl.

#!/usr/bin/perl use strict; use warnings; $i=0; while (1) {   print "testing $i\n" ;   $i++ ;   sleep(1); }

i have compiled code using 

perlcc -o compiled while.pl

then executed normal code while.pl , compiled code compiled. observed memory , cpu usage using ps command 

ps axo %cpu,%mem,command | grep "while\|compiled"  0.0  0.0 /usr/bin/perl ./while.pl 0.0  0.1 ./compiled

so questions are:

  • why compiled code takes more memory compared while.pl?
  • and how avoid memory usage of compiled perl code?

perl code compiled. doing compiling in advance instead of @ run-time.

it takes more memory load compiled form @ run-time because loading compiled-form loader on top of that's loaded.
