I tried it on a mail folder I have around: 20299155 Unzipped 5719754 Gzipped -1 4761790 Gzipped -9 4795281 Gzipped (default) Not much win in size over the default, but definately better than -1. In terms of time: time gzip [14:45:05] wesley:~/Library/MailArchive $ time gzip \#linux.kernel.2001-02.gz# real 0m7.041s user 0m4.870s sys 0m0.150s [14:45:14] wesley:~/Library/MailArchive $ !gun gunzip \#linux.kernel.2001-02.gz#.gz [14:45:21] wesley:~/Library/MailArchive $ time gzip -9 \#linux.kernel.2001-02.gz# real 0m7.732s user 0m5.530s sys 0m0.160s [14:45:34] wesley:~/Library/MailArchive $ gunzip \#linux.kernel.2001-02.gz#.gz [14:46:26] wesley:~/Library/MailArchive $ time gzip -1 \#linux.kernel.2001-02.gz# real 0m5.661s user 0m2.830s sys 0m0.220s So, in general, I just leave things alone unless I want things to run faster. -- Alan Shutko - In a variety of flavors!
