Linux压力测试之stressapptest

上一篇谈到使用stress工具进行Linux的压力测试，这篇则使用stressapptest工具进行Linux压测。

1.stressapptest用法

-s: number of second to run the application       测试时间      
-m: number of memory copy threads to run          复制线程数  (Memory Copy)    
-i: number of memory invert threads to run        反转线程数 (Invert Copy)   
-c: CRC check                                     CRC 校验 (Data Check)
-C: number of memory CPU stress threads to run    CPU压力线程数      
-M: Megabytes of ram to run                       尽可能测试最大的可用存储空间，（设置超过了memfree，就会被kill） 

2.使用举例

下面测试100M内存，测试时间100s

stressapptest -M 100 -s 100

测试成功的log

[root@Sweep:/oem]# stressapptest -M 100 -s 3
