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.

If your .cshrc is big, it might slow things down considerably - it's read on every sub-shell. -- Amos Shapir amos@taux01.nsc.com or amos@nsc.nsc.com National Semiconductor (Israel) P.O.B. 3007, Herzlia 46104, Israel Tel. +972 52 522261 TWX: 33691, fax: +972-52-558322 34 48 E / 32 10 N (My other cpu is a NS32532)

All that this does is to prevent the reading of the .cshrc file (and of course any files sourced by .cshrc, such as the .alias file that many people (at this site, at least) use). However, sh will still be faster. -- jeffm@uokmax.UUCP | Arkansas state motto: At Least We're Not Oklahoma. | Jeff Medcalf +-----------------------------------------------------------+ ----------------| Artificial Intelligence?
