Subject Re: CouchDB presentation in Portland tonight

Thanks Jan!  I suspected that the slower performance from CouchDB was
caused by a combination of HTTP latency and frequent disk flushes.
Your articles help give me the big picture of those tradeoffs.  I will
definitely emphasize CouchDB's fault tolerance and distributability
tonight.
