That can’t be right, all reports I have read about comparing xz with gzip tells me that xz will have better compression but at a slower speed than gzip.
Have you run a test of gzip at the same compression level with the same data?
I don’t doubt that xz will be smaller, I doubt it will be quicker.
xz -0is faster than gzip and has a higher compression ratio.That can’t be right, all reports I have read about comparing xz with gzip tells me that xz will have better compression but at a slower speed than gzip.

This is actually stated in the xz man page:
-0 is sometimes faster than gzip -9 while compressing much better.With a random test file on my system,
xz -0was 3 times as fast while achieving the same compression asgzip -6.
