I am writing a media transcoding server in which I would need to move files in the filesystem and till now I am in the dilemma of whether using java renameTo can be replaced by something else that would give me better performance. I was considering using exec(“mv file1 file2”) but that would be my last bet.
Anyone has had similar experiences or can help me find a solution?
First of all,
renameTois likely just wrapping a system call.Secondly, moving a file does not involve copying any data from the file itself (at least, in unix). All that happens is that the link from the old directory is removed, and a link from the new directory is added. I don’t think you’re going to find any performance improvements here.
