as i have said in the disclaimer, i'm definitely not bashing or blaming mongodb for anything. when you read it, you will see that i have done a 30K/sec load testing. the url it was pointed at was doing writes to mongodb. it opened every connection, wrote to the db and closed the connection. this is a huge success for mongodb. the problem is, when you send every single read query to mongodb under a heavy load, within a few seconds, it will just accept connections and will not respond to queries. this is definitely not the case for writing. writing handles them very well. i really would like to know how we screwed there.
