There's a minimum of 4 Http Requests. There is about 6 SQL queries
to load a user. So, if there is 2 nodes, you have minimum 12
queries for an uncached user. It really all depends how big the
cache can be. Couldn't a million users be cached on a pretty
inexpensive box? My laptop has 32 gig ram. 10K per user is 10 gigs
for a million users.<br>
<br>
Then, depending on UserSession ownership setting, you have
pulling/grabbing/replication of the client sessions as you hop
between nodes. This is the one that can't be fixed. I don't know
how much of a big deal it is.<br>

<div>Is this a high priority for 1.9 or should it
be 2.x? We may be able to put it into 1.9.2 if
required.</div>

<div>I'd like feedback on how useful folks think
it would be as well as feedback on the proposed
implementation.</div>
