It's still orders of magnitude slower than #ZST . I haven't done testing in terms of best use cases for XZ, but a real quick test of the Debian 13 Gnome Live CD had the following results on my hardware.
CPU: Ryzen 9 8945HS
RAM: 64 GB DDR5 @ 5,600 MT/s
Storage: Western Digital Black 4 TB M.2 SSD in PCIe Gen 4x4 M.2 slot
Source: 4,102,389,760 bytes
ZST: 4,062,396,293 bytes
XZ: 4,047,963,404
ZST time taken: 2 seconds
XZ time taken: 1 minute 50 seconds
XZ saved an extra 15 MB on a 4.1 GB input.

I love playing around with #compression
In this case, it's all text-based data in csv and xml formats.

#bzip3 is freaking amazing, yo.

Anyone tried latest #jpackage on #debian? Users report that they cannot install the deb package, because #zst compression is unsupported. https://github.com/JabRef/jabref/issues/9472 #java #jdk #jlink #opensource
