Why does my /bin/csh take longer than /bin/perl?

Okay, so I have two "Hello, world!" scripts, "test.pl" and "test.sh".
Code:
#!/bin/perl -w
use strict;
print "Hello, world!\n";

Code:
#!/bin/csh
echo Hello,\ world!

When I run test.pl, it runs instantly, always. When I run test.sh, it takes anywhere between 4 and 22 seconds!

I'd like to know what could possibly be causing this.


Some facts of interest:
  • I am connected to a remote server via PuTTy (telnet).
  • which csh returns "/bin/csh", which is not a link of any kind.
  • which perl returns "/bin/perl", which is actually a symbolic link to "../perl5/5.8.4/bin/perl".
This is my first time working with csh. Is csh really just that slow?
