Right now, I have upgraded my -current machine from February 13 to April 26. I were pleased with change to dir allocation in FFS, but here are my unpleasant test results (UDMA33, partition is 3 GB where 1 GB is free, soft-updates are enabled): Old system New system time tar xvfz ports.tar.gz real 8m13.773s real 13m48.368s user 0m3.240s user 0m3.167s sys 0m9.371s sys 0m11.329s time rm -r ports real 4m53.255s real 2m20.904s user 0m0.336s user 0m0.295s sys 0m2.565s sys 0m3.230s rm -r is much faster, but tar xvfz is much slower. Furthermore, it was possible to work on another console in an old system without any big impact when tar xvfz was run, but on new system, I have to wait very long time for any disk operation (when tar xvfz runs). For example, I have to wait from 2 to 30 seconds on ls -l command. ??? -- Rudolf Cejka (cejkar@dcse.fee.vutbr.cz; http://www.fee.vutbr.cz/~cejkar) Brno University of Technology, Faculty of El.
