Per the post, the speedup on decompress is _13x_ while the size is 1.008x.

For those figures, this will be better total time for you if your computer network connection is faster than about 1.25mbit/sec. For a slow arm computer with an XZ decompress speed of 3MB/s the bandwidth threshold for a speedup drops to _dialup_ speeds.

And no matter how slow your network connection is and how fast your computer is you'll never take more than 0.8% longer with this change.

For many realistic setups it will be faster, in some cases quite a bit. Your 54MB XZ host should be about 3% faster if you're on a 6mbit/sec link-- assuming your disk can keep up. A slow host that decompresses xz at 3MB/s w/ a 6mbit link would a wopping 40% faster.
