The compression level -9 is overkill and too heavy for old hardware. A better
compression
level would be -3. See effects of various compression levels e.g. at:

results
-------
The -9 vs. -3 in the tests were 13.3 seconds vs. 3.2 seconds (10x),
where compression gain was neglible in higher levels.
In contrast bzip2 -1 took *18.4* seconds.
