From 7a4f54688ee9503c5bf9fcd7a88c4b4b33c36572 Mon Sep 17 00:00:00 2001 From: Bassu Date: Sat, 9 Nov 2013 02:16:38 +0500 Subject: [PATCH] Explain 'zfs list -t snap -o name -s name' speedup Commit 0cee240 from FreeBSD dramatically speeds up 'zfs list' performance assuming you're only interested in the dataset names. This optimization should be mentioned in the man page to allow end users to take advantage of it.
