Then, first do this: "time scp /tmp/bigfile.tar.gz localhost:/tmp/bigfile_copy.tar.gz". This will literally make a copy of that big file, but will route through most of of the network stack. Make a note of how long it took. And also be sure your /tmp partition is big enough for two copies of that big file. Now, repeat that, but instead of copying to localhost, copy to...
