Resource Management

Dedicated Server Resource Control

# CPU Pinning Configuration
cpuset_root=/cpuset
cpuset_cpu_exclusive=1
cpuset_mem_exclusive=1

# Process Priority Assignment
echo $PID > /cpuset/high_priority/tasks

# Memory Management
echo 1 > /proc/sys/vm/zone_reclaim_mode
echo 0 > /proc/sys/kernel/numa_balancing

Virtual Server Resource Distribution

# Resource Allocation Policy
CPU Shares: 1024 (default fair-share)
Memory Balloon Driver: enabled
