+### Limiting CPU Usage During Build
+
+On Linux, you can use cpulimit to restrict CPU usage of intensive build processes:
+
+```bash
+# Limit by process name
+cpulimit -e rustc -l 50  # Limits rustc to 50% CPU
+cpulimit -e clang -l 50  # Limits clang to 50% CPU
+
+# Or limit by PID
+cpulimit -p PID -l 50
+```
+
+On Windows, use Process Lasso or Process Hacker to set CPU affinity and priority:
+1. Open Process Lasso/Process Hacker
+2. Find rustc.exe or clang.exe processes
+3. Right click -> Set CPU Affinity/Priority
