首先运行vmstat检查CPU、内存和交换空间使用情况，再通过iostat分析磁盘I/O活动，高等待时间或低空闲内存表明存在性能瓶颈。If Linux system performance is slow, use vmstat and iostat to identify bottlenecks: 1. Run vmstat to check CPU, memory, and swap usage. 2. Use iostat to analyze disk I/O activity. High wait times or low free memory indicat
e potential issues.
