bcoz bash-completion is known to cause performance problem to bash...

well, I'm running 32bit windoz...

bash is also known to be a *piece of crap* in I/O, done.
however, these exemples aren't representative, specifically the first
one since you have the interactive initialisation. a r/w loop would be
more representative (1000 times is sufficient)
i.e. :
v2$ time bash -c 'i=0; while (( (i+=1) < 1000 )); do while read -r; do
echo -E "$REPLY"; done < /etc/passwd; done > /dev/null'
real 0m25.965s
user 0m2.838s
sys 0m22.494s
# pdksh
v2$ time ksh -c 'i=0; while (( (i+=1) < 1000 )); do while read -r; do
echo -E "$REPLY"; done < /etc/passwd; done > /dev/null'
real 0m8.250s
user 0m0.764s
sys 0m7.065s
v2$ time ksh88 -c 'i=0; while (( (i+=1) < 1000 )); do while read -r; do
echo -E "$REPLY"; done < /etc/passwd; done > /dev/null'
real 0m1.270s
user 0m0.296s
sys 0m0.810s
v2$ time ksh93 -c 'i=0; while (( (i+=1) < 1000 )); do while read -r; do
echo -E "$REPLY"; done < /etc/passwd; done > /dev/null'
real 0m1.472s
user 0m0.374s
sys 0m0.967s
the -i doesn't change anything, bash is still so ssslllooowwww !

no problem, here, except a windows memory exhausted ! then bash died...
almost the first time I see this windows box !!!
maybe you launch too many processes at a time ?
however, I propose you to modify your mkperlmanpdfs script using the
attached parallel shell script... please, keep the copyright, thanks :-)
first time posted on
http://www.mail-archive.com/ast-us...@research.att.com/msg00942.html
i.e. :
cd /tmp/man
cat << 'EOF' > mkperlmanpdfs
ls /usr/lib/perl5/5.10/pods |
sed 's|\.pod||;s|^|man2pdf -n |' |
parallel
EOF
chmod +x mkperlmanpdfs
MANPATH=$PWD ./mkperlmanpdfs
no memory exhausted and only 98% cpu :-)
elapsed time is 425 seconds (aka 7+ minutes) on a Q6600.

no problem here ?

out of topic.

well, and how do you expect I test your man2pdf script the right way w/
these missing pieces ?
for instance, I wrote them using a simple a one liner... and they seems
to make it :-P
