I think that your messages_nnl.gz can be processed faster with

Folding makes it slightly slower.
I managed to create another file without private data using the script
i=0
j=0
while [ $i -lt 10 ]; do
while [ $j -lt 8000000 ]; do
printf "%s " $RANDOM
((j++))
done
printf "%s" "connect"
((i++))
done> largefile
I have tried the code above (which, BTW, puts the 10 "connect" together
at the end of the file. Not sure that is what you intended) and still I
can't see any differences between gzip and zutils. Take into account
that the times in my last mail were from my slow machine (AMD K6-2 450
MHz). On my desktop machine both gzip and zutils take about 1.2s to
zgrep largefile.gz.
Best regards,
Antonio.
