I have done memory test on my cloud instance with Sysbech utility.
Using following command:
sysbench --test=memory --memory-block-size=1K --memory-scope=global --memory-total-size=100G --memory-oper=write run
During the Run:
TOP command result
I never found Mem % is increased. but CPU usage increased upto 100%
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
5664 root 20 0 78036 2704 1908 S 99.5 0.4 0:09.42 sysbench
1 root 20 0 19276 500 348 S 0.0 0.1 0:00.81 init
2 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kthreadd
is it strange ?
What does Memory test in Sysbench actually mean ?
