Perl's startup time also depends on the modules you load:
The following is a simple loop that runs a perl program doing nothing
(executing an empty statement) but firt loading a different set of
modules for the task. The loop repeats it 1000 times:
# No extra modules:
$ time for i in `seq 1000`; do perl -e ''; done
real 0m5.093s
user 0m1.676s
sys 0m2.524s
# Asterisk::AGI:
$ time for i in `seq 1000`; do perl -MAsterisk::AGI -e ''; done
real 0m9.400s
user 0m6.368s
sys 0m2.060s
# MySQL access:
$ time for i in `seq 1000`; do perl -MDBI -MDBD::mysql -e ''; done
real 0m40.964s
user 0m33.122s
sys 0m5.416s
# Asterisk::AGI and MySQL access:
$ time for i in `seq 1000`; do perl -MAsterisk::AGI -MDBI -MDBD::mysql -e '';
done
real 0m45.898s
user 0m36.798s
sys 0m6.048s
