stress:
https://fossies.org/linux/privat/stress-1.0.4.tar.gz/
stress-ng

https://kernel.ubuntu.com/~cking/tarballs/stress-ng/
補充：其他工具
2. 安裝stress
tar -xzvf stress-1.0.4.tar.gz
cd stress-1.0.4/
./configure
make
make install
如果在嵌入式linux系統上做壓測，可以使用對應的交叉工具鏈編譯，然後再將編譯的目標文件load到開發板，比如rk3308:
tar -xzvf stress-1.0.4.tar.gz
cd stress-1.0.4/
./configure CC=arm-rockchip-linux-gnueabihf-gcc --host=arm-linux --prefix=/home/rick/share/stress-1.0.4/bin
make
make install
用法
stress --help
Usage: stress [OPTION [ARG]] …
-?, --help show this help statement
–version show version statement
-v, --verbose be verbose
-q, --quiet be quiet
-n, --dry-run show what would have been done
-t, --timeout N timeout after N seconds
–backoff N wait factor of N microseconds before work starts
-c, --cpu N spawn N workers spinning on sqrt()
-i, --io N spawn N workers spinning on sync()
-m, --vm N spawn N workers spinning on malloc()/free()
–vm-bytes B malloc B bytes per vm worker (default is 256MB)
–vm-stride B touch a byte every B bytes (default is 4096)
–vm-hang N sleep N secs before free (default none, 0 is inf)
–vm-keep redirty memory instead of freeing and reallocating
-d, --hdd N spawn N workers spinning on write()/unlink()
–hdd-bytes B write B bytes per hdd worker (default is 1GB)
Example: stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 10s
Note: Numbers may be suffixed with s,m,h,d,y (time) or B,K,M,G (size
3. 安裝stress-ng
tar -xvJf stress-ng-0.10.15.tar.xz
cd stress-ng-0.10.15
make
make install
stress-ng用法:
cpu
stress-ng --cpu 24 --cpu-method pi --cpu-load 100
內存
stress-ng --vm 4 --vm-bytes 12g --vm-method all --vm-keep -v
Example: stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 10s
Note: Numbers may be suffixed with s,m,h,d,y (time) or B,K,M,G (size).
