C 11.11 [3] Besorgen Sie sich eine geeignete Datei (etwa ein größeres tar -Ar-
|
|
|
|
|
chiv mit Quellcode, vielleicht für den Linux-Kernel) und komprimieren Sie
|
|
|
|
|
sie jeweils mit gzip , bzip2 und xz . Messen Sie dabei die Ausführungszeit
|
|
|
|
|
durch ein vorgesetztes time . Wie verhalten die Laufzeiten und die Kompri-
|
|
|
|
|
mierungsraten sich zueinander?
|
|
|
|
|
C 11.12 [2] Experimentieren Sie mit der Datei aus der vorigen Aufgabe und
|
|
|
|
|
vergleichen Sie die Laufzeit und die Größe des Resultats für xz mit verschie-
|
|
|
|
|
denen Effizienz-Optionen. Was ist der Unterschied zwischen -1 und -6 und
|
|
|
|
|
zwischen -6 und -9 ?
