Xz-utils 5.6.0 was released last Friday. It features a much faster decompression code on all platforms but on x86_64 in particular, it is 60% faster in my testing. It also aligns better current practices of enabling multi-threading by default (always with a default memory limit of 25% of the system physical memory).

Sebastian Andrzej Siewior has uploaded it to experimental and after a few fixes for integration (due to extra output on stderr in particular), has uploaded xz-utils 5.6.0-0.2.

I expect tests to pass now considering they almost all succeeded with the first upload.
I am aware of tweaks to other packages too but I'm not sure they will actually be needed with this new upload and since they relate to pristine-tar and/or dpkg, I think it's probably better to be sure first due to the ongoing migrations.

Thanks.
