Multi-threaded

1. Record the server selection start time

2. If the topology wire version is invalid, raise an error

3. Find suitable servers by topology type and operation type

4. If there are any suitable servers, choose one at random from those
   within the latency window and return it; otherwise, continue to step #5

A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

# typical of the behavior, though they are the results of two particular

# Brubeck with Gevent

$ siege -c500 -t10s localhost:6767/brubeck

Lifting the server siege...      done.
