Is sh script faster than csh script ?

[Peng Lee]

------------------------
137 % cat iput
#!/bin/sh
#
#  intelligent put
#
case $# in
[01])   echo "Usage: $0 host filename [dis directory]";;
*)      host="$1"; shift
        user=`nfrh $host`
        rcp -r "$1" "$host"."$user":"$*" &
esac

138 % cat iput.c
#!/bin/csh
#
#  intelligent put ( csh script )
#

set user=`~/bin/nfrh $1`
rcp -r "$2" "$1"."$user":. &

139 % time iput bloom iput

-------------------------
It seems that csh used a lot more memory, io, and had 2 pages fault.

Would any unix.wizards out there explain why csh is so slow?  Or did I
use the wrong command in the script?   

This test is done VAX.
