hi,
first of all, my uname -a: FreeBSD oberon.cs.uchicago.edu 4.4-RELEASE FreeBSD 4.4-RELEASE #0: Tue Sep 18 11:57:08 PDT 2001 murray@builder.FreeBSD.org:/usr/src/sys/compile/GENERIC i386
now:
the following perl script takes 8 minutes to execute on both of my freebsd systems (two AMD K6-2 300s):
cat 80megfile.ps > perl cat.pl > output.ps
cat.pl:
while($_ = <STDIN>) {
print $_;
}
however,
cat 80megfile.ps > cat - > output.ps
takes 2 seconds on the same system.
running that perl script on a debian system takes a few seconds also as does the cat -.
what the hell is going on? perl seems to work reasonably other than this.
my perl version: This is perl, version 5.005_03 built for i386-freebsd
this is the perl that came with a cd install of my freebsd system which i downloaded off the freebsd.org web site as an iso.
yours,
steve
