I have heard about he xz compressor, so I was interested on how 7zip and xz perform maxed-out:

7z a -t7z -m0=lzma -mx=9 -mfb=255 -md=256m -ms=on scan-build-2011-07-02-1.7z scan-build-2011-07-02-1
11.87MiB - 12445530 scan-build-2011-07-02-1.7z

xz -zkc -Fxz -9e -M5GB --lzma2='dict=256Mi,nice=273,mf=bt4' scan-build-2011-07-02-1.tar > scan-build-2011-07-02-1.xz
12.14MiB - 12726004 scan-build-2011-07-02-1.xz

I didn't measure time, but it wasn't very long; xz took longer, because it doesn't support multithreading. Both required 3.5GB of memory at the peek.
