Performance
my QEMU benchmark
QEmu guest system openSUSE 10.2, command is
1:time (for i in $(seq 1 1 10000); do echo $i>>file;done) 2:time (for i in $(seq 1 1 10000); do echo $i>>/dev/null;done)
host command times without kqemu times with kqemu times native XEON 1 17-7-2 XEON 2 16-7-1 PIV 1 20-8-3 6-2-2 1-0-0
my easy benchmark
Goal: Get a rough impression of system power Command is
time (for i in $(seq 1 1 10000); do echo $i>>file;done)
Or if bash is not available, write a script that does this and call it using time
