 * Hi, I have been working on speeding up my multisite installations…. and was baffled
   for a while by a dm=hash string was and why it was taking up to 600ms to load
   and slowing down my whole site loading time by 1/2 a second or more. Eventually
   found this article which explains what the dm? string was.

 * His suggested fix was to either disable remote login or to add in an async snippet.
   I tried the async and it didn’t seem to make any difference, but changing to 
   remote login dropped my site loading time down by .58 seconds and dropped my 
   requests from 10 to 9.
 * I’m not in all honesty remotely sure what the remote login is for so I am pretty
   happy, but it seems that getting it to load asynchronously would be useful.

 * The purpose of the script is to complete the remote login. If you load the script
   async then the original page loads not logged in. If you & your users are fine
   with that then switching to async should be fine.
