+## Speed
+
+In quick testing, I managed about 250MiB/s from Lustre to Lustre, and about 1GiB/s from tmpfs to tmpfs. It's not ideal, but it's fast enough for a lot of uses.
 
 ## Example
 
-Sender:
+##### Sender
+
+The Sender makes a test file to send to their friend:
 
 ```
 # Make a junk 1GiB file
 $ dd if=/dev/zero of=some_file bs=1GiB count=1
+```
+
+And then uses `pipe-give` to send it:
 
+```
 $ pipe-give some_file
 
-Your transfer ID: XESXdZMT
-    and password: 985126401
+Your transfer ID: dzbGPpE3
+    and password: 688815576
 
 Please enter this at receiver.
 
 Remember you must be on the same node.
 
+This node is: login13
+
     [Ctrl-C to cancel.]
 ```
 
-Sender now gives ID and password to receiver, who enters them at the prompts:
