Er, I was just pointing out that your conclusion ("lzma isn't the right
thing ... p7zip seems must faster and needs a lot less ram") is rather
dodgy because you used an option that lzma specifically warns against
using.  From my own experiencd I know that lzma consumes much more
memory with -9 than with the default setting.

So though I'm certainly in no position to repeat these tests myself, I
think others should be wary of your results.
