I have a large folder, 2TB, with 1000000 files on a Linux machine. I want to build a package with tar. I do not care about the size of the tar file, so I do not need to compress the data. How can I speed
tar up? It takes me an hour to build a package with
tar -cf xxx.tar xxx/. I have a powerful CPU with 28 cores, and 500GB memory，is there a way to make
tar run multithreaded?
Or, alternatively, is there any good way to transfer a large number of small files between different folders and between different servers? My filesystem is ext4.
