I just tested extracting a 10 MB .bz2 file to /dev/null on our 800 MHz server: It took 57 seconds. Recompressing the result to .gz, extracting that took only 5 seconds. The installation data is roughly 30 times that much. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
