   did some tests between zstd-1, zstd-3, and lz4 for zfs compression
   
   In terms of writes, lz4 is by far the fastest, followed by no compression, zstd-1, and zstd-3. All are fairly close though.
   
   Read-wise, lz4 is by far the fastest, followed by none, and then zstd is substantially slower for sequential. Random reads are pretty close though.
   
   For reference, I also tested without compression, which seems to be between zstd-1 and lz4.
   
   All tests were done on a Rocky Linux 10 VM inside a Proxmox VE 8.4.1 hypervisor with a Ryzen 5900X CPU and a ZFS mirror with a Crucial P5 Plus and T-Force Cardera A440 Pro, both 2 TB.
