Is this normal to have CPU at 50% for a simple ftp task?

For simple FTP (File Transfer Protocol) tasks, a CPU usage of 50% is usually not normal.FTP tasks, such as uploading or downloading files, do not usually result in high CPU usage, because such operations are mainly dependent on network bandwidth and disk I/O (Input/Output) performance, rather than CPU processing power.
The following are some possible causes of high CPU utilization during FTP operations:
1. Network problems: If the network connection is unstable or slow, the system may need to retry the connection or process the packets frequently, which may increase the CPU utilization.
2. Software problems: The FTP client or server software used may have efficiency problems or bugs, resulting in abnormal CPU utilization.
3. Virus or malware: The system may be affected by viruses or malware, which may run in the background and consume CPU resources.
4. Insufficient system resources: If the system itself has insufficient resources (e.g., insufficient memory leading to frequent disk swapping), then even simple tasks may result in high CPU usage.
