Comment:

 Yawning suggests `xz -9e` as an alternative to `xz -9`.  Here are some
 results:

 || '''Command''' || '''Decompressed size''' || '''Compression time''' ||
 '''Compressed size''' || '''Decompression Time''' ||
 || `xz -9` || 13G || 56m54.372s || 172M (1.29%) || 0m33.692s ||
 || `xz -9e` || 13G || 105m23.670s || 115M (0.86%) || 0m30.137s ||

 That's 67% of the current size for an additional 88% of compression time,
 but with 10% faster decompression.  Worth considering after switching
 CollecTor to new hardware, I'd say.  Re-opening.
