This occurs because the server must compress requested files into a single ZIP archive in real-time (on-the-fly) to facilitate the download, which consumes significant CPU and memory resources. Why This Happens Resource Management
; Increase maximum execution time for long compression cycles max_execution_time = 300 ; Increase memory limits to allow larger fly-compression buffers memory_limit = 512M ; Ensure post and upload limits match your data expectations post_max_size = 10G upload_max_filesize = 10G Use code with caution. Transfer the folders directly to your hard drive
