-Subject: [PATCH] salt-master: Increase command_timeout to 15s
+Subject: [PATCH] states: maas: Batch apply linux state with `-b 4`
-Default command timeout (10s) is sometimes too small for all minions
-to return within the required timeslot. Increase it by 50%.
+Applying heavy states like linux.network on multiple nodes in
+parallel might lead to spurious timeouts on slower systems.
-While at it, increase the timeout used for executing the "linux"
-state against all nodes to 60s, just to be on the safe side.
+Compromise between speed and realiability by applying this state
+in batches of 4 nodes at once.
+
+While at it, increase global command_timeout to 15s on Salt master,
+since default command timeout (10s) is sometimes too small for all
+minions to return within the required timeslot. Increase it by 50%.
