+##A tip to speed things up##
+If you have openssh >= 0.4, you can make use of the "ControlMaster"
+feature. This allows you to reuse an existing connection. Therefore
+if you keep a connection open, you won't have to authenticate every
+time.
+
+Add the following to your ~/.ssh/config file:
+
+ Host server_name
+ ControlMaster auto
+ ControlPath ~/.ssh/master0%r@%h:%p
+
+You can also se the Host to "*", if you want to use it for all
+connections. I usually have an interactive ssh connection to my home
+computer open, so I don't need to do anything more. But if not, you
+can always run:
+
+ ssh -Nf server_name
+
+which will open up a background connection, which you can then reuse
+for all of your notmuch commands.
