服务器清理内存使用率

# 示例：Python中的内存泄漏检测与修复
import gc

def leaky_function():
    global data
    data = [i for i in range(1000000)]  # 不释放内存

# 使用gc模块检测泄漏
gc.collect()

// 示例：Java中的内存池管理
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.BlockingQueue;

public class MemoryPool {
    private BlockingQueue<byte[]> pool;

    public MemoryPool(int maxSize, int chunkSize) {
        pool = new ArrayBlockingQueue<>(maxSize);
        for (int i = 0; i < maxSize; i++) {
            pool.offer(new byte[chunkSize]);
        }
    }

    public byte[] allocate() throws InterruptedException {
        return pool.take();
    }

    public void free(byte[] chunk) throws InterruptedException {
        pool.put(chunk);
    }
}

# 示例：Linux系统中清理缓存
sudo sync; sudo echo 3 > /proc/sys/vm/drop_caches
