[cobalt-users] tar not compressing?

["FantasticMoms.com" <admin@xxxxxxxxxxxxxxxxx>]

I just noticed tarring my log files doesn't seem to make them smaller.

I just tarred web.log by using the following :

tar cvfp /home/sites/site4/logs/weblog.tar /home/sites/site4/logs/web.log

and the resulting listing showed :

-rw-r--r--    1 root     site4    12748800 Feb 23 18:49 weblog.tar
-rw-r--r--    1 root     site4    12744014 Feb 23 05:07 web.log

So the tar is actually a little bit bigger.  What am I doing wrong?
