When uploading a large number of files, we recommend you limit the number of FTP connections. Here are instructions to limit FTP connections in FileZilla:
- Add the FTP details in FileZilla > File > Site Manager
- Go to File > Site Manager > Select the FTP server
- Go to Transfer Settings
- Checkmark [*] Limit Number of simultaneous connections
- Enter 4 in Maximum number of connections
- Click OK to save the settings.
- Close and relaunch File Zilla
- Done!
More connections do not necessarily make the upload faster, but they can get your IP blocked by the server firewall due to an excessive number of FTP connections.
