使用sysbench对Oracle做基准测试(五) MEMORY

[root@localhost sysbench]# sysbench --test=memory help 
sysbench 0.5:  multi-threaded system evaluation benchmark


memory options:
  --memory-block-size=SIZE    size of memory block for test [1K]                    内存块的大小
  --memory-total-size=SIZE    total size of data to transfer [100G]                 操纵内存的总体数量
  --memory-scope=STRING       memory access scope {global,local} [global]           内存的访问范围
  --memory-hugetlb=[on|off]   allocate memory from HugeTLB pool [off]               是否从HUGEPAGE中分配内存
  --memory-oper=STRING        type of memory operations {read, write, none} [write] 内存操作方式读或者写
  --memory-access-mode=STRING memory access mode {seq,rnd} [seq]                    内存访问方式 顺序还是随机
