Tips & Precautions
Useful tips and points to consider when using axel.
Performance Optimization
- Adjust the value of the `-n` option considering your network environment and server load. Too many connections can overload the server or lead to being blocked.
- For downloading large files, axel can be more efficient than `wget` or `curl`. The resume feature is particularly useful in unstable network environments.
Precautions
- Some web servers may limit or block multiple connections. In such cases, axel may not function correctly, or your IP might be blocked.
- If the downloaded file is corrupted, axel automatically checks integrity unless the `-k` option is used, but this cannot always be trusted. For important files, it is advisable to verify their integrity using hash values after downloading.
