I have a Java program which is launched through command-line by a Bash script, which is in turn called at various intervals by cron.
There are several operations performed by this program, the first being the copy of a possibly large number of more or less large files. (Anything from 10000 files of 30 KB to 1 big 1 GB file, but both of these are edge cases.)
I am curious about how this step should be accomplished to ensure performance (as in speed).
I can use either Bash's cp function, or Java 7's Files.copy(). I will run my own tests but I'm wondering if someone has any comparison data I could take into account before deciding on an implementation?
