Hi, I'ven't had a lot of time. Main problem is currently: How can I get an "old" file system on my test machine ?
I'll tried to simply copy a whole structure with system tools (scp and so on) an I get ls -lR => ~10sek on the old system, then less 1 sek (cache data) time find . -type f -print0 | xargs -0 cat > /dev/null real 2m1.606s user 0m0.050s sys 0m0.480s -------- So on the new sytem ls -lR => <1sek (umount before) time find . -type f -print0 | xargs -0 cat > /dev/null real 0m8.764s user 0m0.030s sys 0m0.560s from cache: time find . -type f -print0 | xargs -0 cat > /dev/null real 0m0.194s user 0m0.010s sys 0m0.230s -----------------------How should I test a way to optimize it, when I can not get the "dirty" state ?
Bye, Peer
