I compressed 897M worth of Icecast log files (similar to Apache logs) and got the following results:

-rw-r--r-- 1 root root 32M Jun 27 17:41 logs-201109-201406.mx1.7z
-rw-r--r-- 1 root root 37M Jun 27 18:05 logs-201109-201406.mx6.7z
-rw-r--r-- 1 root root 27M Jun 27 17:50 logs-201109-201406.tar.bz2

7z with mx1 gives me a smaller file than mx6, and so does bz2.

Command line was simply "7zr a -mx# file folder"

Not sure this is a bug, but thought it was worth reporting...
