I'm still having the same problems after recompiling the kernel a few
times with different options. Ken, I don't know how to check against
the 32 v 64 bit. uname reports:
Linux hojo-lfs-6.8 2.6.38.2-LFS6.8 #1 SMP Mon Apr 18 20:35:16 MDT 2011
x86_64 x86_64 x86_64 GNU/Linux
I have picked out a shell script that runs very slowly from the
configure script from openssh. On a stable system the script runs as
fast as expected:
Script:
#LS nuisances.
for as_var in \
LANG LANGUAGE LC_ADDRESS LC_ALL LC_COLLATE LC_CTYPE LC_IDENTIFICATION \
LC_MEASUREMENT LC_MESSAGES LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER \
LC_TELEPHONE LC_TIME
do
if (set +x; test -z "`(eval $as_var=C; export $as_var) 2>&1`"); then
eval $as_var=C; export $as_var
else
($as_unset $as_var) >/dev/null 2>&1 && $as_unset $as_var
fi
done
The time on the script my box:
real 0m5.780s
user 0m0.030s
sys 0m5.710s
I have to run this script in a loop roughly 300 times on the stable
box to approximate the LFS run. If I run this in a loop on the LFS
box top shows the following while bash only consumes around 7 to 9% of
the cpu and a scant of memory.
Cpu(s): 0.0%us, 25.7%sy, 0.2%ni, 74.0%id, 0.0%wa, 0.0%hi, 0.2%si, 0.0%st

I'm not sure how to do that. Do you have a hint or page to refer me to?
