In the process of moving articles from a FreeBSD box with tradspool to one
with CNFS buffers, and I notice towards the end of the progress that the ZFS
compression achieved with the CNFS buffer is orders of magnitude higher than
the box with tradspool. Same FreeBSD versions, same article set, but was
barely seeing compression on the box with tradspool, but on the box with CNFS:

[news@gatekeeper ~]$ cnfsstat
Class TEXT for groups matching "*"
Buffer TEXT, size: 977 GBytes, position: 608 GBytes 0.62 cycles
Newest: 2023-06-06 11:07:31, 0 days, 0:00:00 ago

$ du -h cycbuffs/
157G cycbuffs/

608GB compressed down to 157GB on the filesystem. :-)
