Ah, very interesting, thanks! It seems that in several cases where the compression ratio is better the compression *and* decompression time explodes a bit. That seems to be a fine property for long-term archival, but probably not so much for something like a packaging system format. In addition requiring much memory is a no-go as we need to be able to build the same binary on multiple architectures where RAM might not be available in TiBs. :) > Is there a possibility for dpkg to gain support for lrzip compressed > packages? I've updated the FAQ to include an entry on .deb compression in addition to the pre-existing .dsc compression: <https://wiki.debian.org/Teams/Dpkg/FAQ#Q:_Can_we_add_support_for_new_compressors_for_.deb_packages.3F> Given the above, it does not seem to me adding lrzip is worth it to be honest. Thanks, Guillem
