Compression is now on by default in recent OpenZFS. If you have reservations, you should probably run a one-liner like this one before upgrading your OS, be it current or stable/13. If you are curious and want to know what will happen, run this one-liner.

I use Synth to build my own packages. On a test system running stable/13, Synth had issues with textproc/py-sphinxcontrib-applehelp@py39.

The bootloader in recent stable/11 always gave me trouble booting the kernel due to having loader_color=”YES” in my /boot/loader.conf. Strangely enough, the same setting is harmless in recent stable/12.

iperf3 results between Chelsio T6225-CR and Intel X710-DA4
I ran two iperf3 tests between two hosts using Chelsio T6225-CR and Intel X710-DA4, respectively. Both NICs are connected to the supervisor interfaces on a Sup8E in a Cisco Catalyst 4500E chassis. Wirespeed is 10 Gbit/s.
