Cross-platform system stress utility to generate controlled system load for CPU, Memory and Network bandwidth. The synthentic load can be controlled by time intervals, load percents and amounts of resources to use.
Available for Windows, Linux and MacOS for both x86-64, ARM64 architectures. Many other Golang supported platforms might be supported, but need to tested for any incompatible feature. The system's max. CPU load limit -cpu-m option is not supported in MacOS/ARM64 platform.
This was started as a fork of NeverIdle code, but now both codes have deviated significnatly and are incomptible to merge, especially after adding control options for CPU and Memory loads.
./NI -cpu 2h5m30s -cpu-d 15m -cpu-p 50 -cpu-m 80 -mem 2.5 -net 4h -cpu duration
Interval of CPU streess (enables CPU stress)
-cpu-d duration
Min. duration for each CPU stress (default 2s)
-cpu-m float
Max limit of system's total CPU load perceent (default 100)
-cpu-n int
Number of CPU cores to stress (default AllCores)
-cpu-p float
Each CPU's load percentage (default 100)
-mem float
GiB of memory to use
-net duration
Interval for network speed test
-net-c int
