What's the compression rate used in your test? I've seen benchmarks for an older version of xz-utils (I think it was called lzma-utils). In that benchmark the most simple compression level was faster and smaller than gzip -9, and bzip2 was outperformed anyways.
I just used the default which should be -6.
Note that tighter compressions needs a bigger dictionary size when unpacking, which can be crap on low-memory systems.
Do you have numbers? We could do some testing in qemu with e.g. 128MB RAM etc.. Or maybe have a look at Slackware who are already using xz for their whole repo. According to them you need at least a 486 and 64MB RAM. Does not look like anything we should worry about. -- Pierre Schmitz, https://users.archlinux.de/~pierre
