Cpulimit is a command-line tool that limits the CPU usage percentage of a process by sending SIGSTOP and SIGCONT signals, without changing scheduling priorities. It adapts dynamically to overall system load and applies the limit to all child processes and threads.

Use cases

• limit cpu usage of a batch job
• prevent a process from eating all cpu cycles
• throttle a background process cpu percentage
• cap cpu usage of a running command
• control cpu consumption of scripts on a shared server

When to choose

• you need to cap real CPU usage percentage rather than adjust nice values
• you want a lightweight C tool with no dependencies on Linux, macOS, or FreeBSD
• you need to throttle batch jobs or background tasks dynamically

When to avoid

• you need per-core or cgroup-based resource isolation
• you want to limit memory, IO, or other resources, not just CPU
• you need a solution integrated with systemd or container resource limits
