You need to add -r parameters to copy the directory to achieve recursive copy, otherwise an error will be reported; 3. Keep the original attributes available -p or more comprehensive -a parameters; 4.

Why is my Linux server running slow?
Common reasons for slowing Linux servers include resource bottlenecks, improper configuration, or excessive background process usage. 1. First check the CPU and memory usage, use the top/htop command to see if there is a high process occupancy, combine free-h to determine whether the memory is insufficient, and pay attention to issues such as web server concurrency and database query not optimized; 2. Then check the disk IO performance, use iostat/iotop to see if the disk %util is close to 100%, identify frequently read and write programs such as database logs, and consider upgrading SSD or optimizing queries; 3. Then check the network delay and number of connections, use ping/traceroute to test network delay, observe the connection status through netstat/ss, and optimize H
