Мужчины!

Как говорил Иисус Христос, если на хвосте у льва висит бирка с надписью
"Хавронья", протри газа свои.

$ head -c $((4<<20)) /dev/urandom |/usr/bin/time xz |wc -c

$ head -c $((8<<20)) /dev/urandom |/usr/bin/time xz |wc -c

Как такое может быть, что user time и system time меняются местами?
