Yes, thanks. I really forgot on this change.
My rough results are now:
Old s./wc enabled New s./wc enabled New s./wc disabled
tar xvfz 8 minutes 4 minutes 14 minutes
rm -r 5 minutes 1 minute 2 minutes
There is another reason for tar "slowness": Current version of
tar seems to be faster than our old system tar: 3m23 against 3m44
for tar xvfz with wc enabled. I think there are even bigger
differences with tar cvfz and tar xvfz with wc disabled.
