xz used compression level 1 out of 9 for this With compression level 5, xz produced the smallest archive at 29 MB, which was 69 smaller than pigz. It also has wrappers for scripts still using LZMA-Utils. In the same 4 seconds, xz compressed the file to just 48 MB, which was 49 smaller than pigz. As for even keeping LZMA-Utils around: dont. lzma files, they are considered a legacy format. +#ifdef CONFIG_XZ +#include +#endif /* CONFIG_XZ */ + xz format allows you to specify compression algorithms, and filters, so.
