Can we see output of

Does tar -tvf tar_test.tar.gz display the files you wanted to tar on standard output ?

Are you sure you used right from file location ?
The /list_of_files is under root(/), is that your working folder ?

Compression ratio depends on what are you compressing.

I checked the GNU version of tar and the only way to auto compress using file extension magic is to use the "a" flag:

Code:

You can also let GNU tar select the compression program based on the
suffix of the archive file name. This is done using �--auto-compress' (�-a')
command line option. For example, the following invocation will use bzip2
for compression:

$ tar caf archive.tar.bz2 .
