I've read all the info I could find re running PG on ZFS: turn off full page writes, turn on lz4, tweak recordsize so as to take advantage of compression, etc. One thing I haven't seen is whether a separate volume for WAL would benefit from a larger recordsize. Or any other tweaks??? -- Scott Ribe scott_ribe@xxxxxxxxxxxxxxxx https://www.linkedin.com/in/scottribe/
