-Parameters for simulation:
+Each client creates a room when it starts up and joins that room plus
+`roomsPerClient` other rooms.
 
-Each document is randomly placed in a collection, with a random
-'bucket' field. Clients sub to 1 bucket in each collection.
+Every `talkativePeriodSeconds`, each client has a
+`chanceClientIsTalkative` probability of being "talkative". If it is
+talkative for that period, it will send one `messageSize` sized message
+every `talkativeMessagesPerSecond` for the duration of the period.
 
-- numCollections
-    how many collections to spread the documents over
-- numBuckets
-    number of buckets per collection.
-
-- initialDocuments: Inital documents added by the server. Probably
-    not usefully combined with maxAgeSeconds
-
-- maxAgeSeconds: How long to leave documents in the database. This,
-    combined with all the various rates, determines the steady state
-    database size. In seconds. falsy to disable.
-
-Per-client action rates:
-- insertsPerSecond
-- updatesPerSecond
-- removesPerSecond
-
-- documentSize: bytes of randomness per document.
-    // XXX make this a random distribution?
-- documentNumFields: how many fields of randomness per document.
-
-XXX also max documents? (count and remove N)
+Old messages are deleted every `messageHistorySeconds` seconds. Old
+rooms are deleted every `roomHistorySeconds`. `roomHistorySeconds`
+should line up with the length a particular client dwells on the site
+(typically part of the phantomjs script used to drive the clients.)
