DRAFT!
test disk I/O
time sh -c "dd if=/dev/zero of=ddfile bs=8k count=250000 && sync"; rm ddfile
test with hdparm direct read:
hdparm -t /dev/sda2
test with hdparm cached read :
hdparm -T /dev/sda2
Stress test memory [fill memory up to 90%]:
stress --vm-bytes $(awk '/MemFree/{printf "%d\n", $2 * 0.9;}' < /proc/meminfo)k --vm-keep -m 1
Stress test cpu/io/vm:
stress --cpu 8 --io 16 --vm 32 --vm-bytes 256M --timeout 100000000s
You can also use cpuburn utility for cpu stress test
load 1 CPU core:
dd if=/dev/zero of=/dev/null
Load more cpu cores:
fulload() { dd if=/dev/zero of=/dev/null | dd if=/dev/zero of=/dev/null | dd if=/dev/zero of=/dev/null | dd if=/dev/zero of=/dev/null & }; fulload; read; killall dd
