here I did some compression comparisons and u can c :

m1999.11.zip        4,264,732  original archive file

testing.cab            1,400,426
testing.rar            1,535,789
Testing.ace            1,700,271
test2.tar.bz2          2,565,178
test1.tar.gz           3,042,154
testing.lzh            4,025,354
test.bh                4,063,632
testing.jar            4,272,214
test.tar              11,120,640
test2.tar             11,120,640

CAB is quite good on compression with RAR & ACE following closely behind BUT I
stated in this thread WinRAR 2.71 supports other O/S besides winDOZES
